reasonable suspicion analysis in Massachusetts

2026"An innocent explanation for an individual's actions 'does not remove [those actions] from consideration in the reasonable suspicion analysis.'" Id., quoting Commonwealth v. DePeiza, 449 Mass. 367, 373 (2007).

2025The judge noted that Rivera's movement was consistent with looking in the side view mirror at the approaching officer, but an innocent explanation for a person's actions "does not remove [those actions] from consideration in the reasonable suspicion analysis." Commonwealth v. Sweeting-Bailey, 488 Mass. 741 , 744 (2021), quoting Commonwealth v. DePeiza, 449 Mass. 367, 373 (2007).

2025The reasonable suspicion analysis examines " the totality of the facts on which the seizure is based." Id., citing Commonwealth v. Meneus, 476 Mass. 231, 235 (2017).

2025Combined with the timing, 8 proximity to the shooting, and observations about the defendant's driving, this gave the officer reasonable suspicion to believe that the defendant had recently engaged in criminal activity. "[T]he value of a vague or general description in the reasonable suspicion analysis may be enhanced if other factors known to the police make it reasonable to surmise that the suspect was involved in the crime under investigation." Commonwealth v. Meneus, 476 Mass. 231, 237 (2017).

2026See Commonwealth v. Warren, 475 Mass. 530, 534 (2016) ("The essence of the reasonable suspicion inquiry is whether the police have an individualized suspicion that the person seized is the perpetrator of the suspected crime); Commonwealth v. Depina, 456 Mass. 238, 243 (2010) (stop based on dispatch is lawful if "the description of the suspect conveyed by the dispatch had sufficient particularity that it was reasonable for the police to suspect a person matching that description").

2026See id. at 536 ("proximity of the stop to the time and location of the crime is a relevant factor in the reasonable suspicion analysis" and "[p]roximity is accorded greater probative value in the reasonable suspicion calculus when the distance is short and the timing is close").

2025Rather, as the Supreme Judicial Court acknowledged in Commonwealth v. Lopes, 455 Mass. 147, 155-156 (2009), quoting Commonwealth v. Lyons, 409 Mass. 16, 19 (1990), the Aguilar-Spinelli concepts of "basis of knowledge" and "reliab[ility]," to the extent they are relevant, are applied in a "less rigorous" manner in a reasonable suspicion analysis.

Warren, 475 Mass. 530, 534 (2016) ("The essence of the reasonable suspicion inquiry is whether the police have an individualized suspicion that the person seized is the perpetrator of the suspected crime); Commonwealth v.

2021"The essence of the reasonable suspicion inquiry is whether the police have an individualized suspicion that the person seized is the perpetrator of the suspected crime." Warren, supra. See Commonwealth v. Depina, 456 Mass. 238, 243 (2010).

2025Reasonable suspicion "must be based on specific and articulable facts, and reasonable inferences therefrom, in light of the officer's experience." Id., citing Commonwealth v. Gomes, 453 Mass. 506, 511 (2009).

2023Then, the officers heard the defendant's claim to be coming from a nearby restaurant they knew had closed thirty minutes earlier, and saw he was heading in the opposite direction from his purported destination. 3 See Commonwealth v. Henley, 488 Mass. 95 , 103 (2021) (defendant's 3 "That there may be an innocent explanation for the defendant's actions 'does not remove [those actions] from consideration in the reasonable suspicion analysis.'" Commonwealth v. Gomes, 453 Mass. 506, 511 (2009), quoting Commonwealth v. DePeiza, 449 Mass. 367, 373 (2007).

2022Cf. Meneus, 476 Mass. at 238 , quoting Commonwealth v. Grandison, 433 Mass. 135, 139 (2001) ("Although the characterization of a particular neighborhood as a 'high crime' area has been recognized as a factor in the reasonable suspicion analysis, . . . we have been clear that '[j]ust being in a high crime area is not enough to justify a stop'").

2017Although the characterization of a particular neighborhood as a “high crime” area has been recognized as a factor in the reasonable suspicion analysis, Commonwealth v. Johnson, 454 Mass. 159, 163 (2009), we have been clear that “[j]ust being in a high crime area is not enough to justify a stop.” Commonwealth v. Grandison, 433 Mass. 135, 139 (2001).

2024Reasonable suspicion "is measured by an objective standard, and the totality of the facts on which the seizure is based must establish 'an individualized suspicion that the person seized by the police is the perpetrator' of the crime under investigation." Commonwealth v. Ford, 100 Mass. App. Ct. 712 , 6 715 (2022), quoting Meneus, supra. When police officers are investigating reports concerning an individual with a gun, the reasonable suspicion analysis "should include . . . the government's need for prompt investigation." Commonwealth v. Stoute, 422 Mass. 782, 791 (1996), quoting United State

2008Because they did not know at that time that the driver of the car was a man, this license information provided a reasonable suspicion to believe that the registered owner of the vehicle was driving with a suspended license. 3 See Commonwealth v. Deramo, 436 Mass. 40, 44 (2002) (“the likelihood that the operator is the owner is strong enough to satisfy the reasonable suspicion standard”).

2004“While it is certainly possible that someone other than a vehicle’s registered owner may be operating the vehicle on any given occasion, the likelihood that the operator is the owner is strong enough to satisfy the reasonable suspicion standard.” Commonwealth v. Deramo, 436 Mass. 40, 43-44 (2002).

2017Although the characterization of a particular neighborhood as a “high crime” area has been recognized as a factor in the reasonable suspicion analysis, Commonwealth v. Johnson, 454 Mass. 159, 163 (2009), we have been clear that “[j]ust being in a high crime area is not enough to justify a stop.” Commonwealth v. Grandison, 433 Mass. 135, 139 (2001).

2017We have held that a “high crime” neighborhood may be a proper factor in the reasonable suspicion analysis, see Commonwealth v. Johnson, 454 Mass. 159 , *245 163 (2009), but “[j]ust being in a high crime area is not enough to justify a stop.” Commonwealth v. Grandison, 433 Mass. 135, 139 (2001).

2025L. c. 111B, § 3."[3] This holding overruled this court's conclusion in Commonwealth v. McCaffery, 49 Mass. App. Ct. 713, 716 (2000), that the reasonable suspicion standard was the appropriate one to determine whether an individual could constitutionally be taken into protective custody under G.

2024See id. at 534-535, 540 . 10In coming to this conclusion, the judge noted that Smerz could not see the front of the defendant's body. 12 After conducting an independent review of the above factors and leaving all determinations of the weight and credibility of the testimony to the trial judge, Scott, 440 Mass. at 647 , we conclude that the officers did not have reasonable suspicion to seize the defendant when the defendant became aware that approximately ten officers were chasing him.

2006When reviewing a judge’s determination on a motion to suppress, “we accept the judge’s subsidiary findings of fact absent clear error ‘but conduct an independent review of his ultimate findings and conclusions of law.’ ” Commonwealth v. Scott, 440 Mass. 642, 646 (2004), quoting from Commonwealth v. Jimenez, 438 Mass. 213, 218 (2002).

2019See Commonwealth v. Clark, 65 Mass. App. Ct. 39, 44-45 (2005) (no reasonable suspicion for stop where individual in "high drug area" left bar, approached defendant, handed "an item" to defendant, and then returned to bar as defendant appeared to count money); Commonwealth v. Ellis, 12 Mass. App. Ct. 476 , 477 5 Although we have not adopted a per se rule that requires officers to be able to identify whether anything is exchanged in order to have reasonable suspicion to believe that a drug transaction has taken place, see Commonwealth v. Stewart, 469 Mass. 257, 263 (2014), citing Commonwealth v.

2017Given that “[s]eemingly innocent activities taken together can give rise to reasonable suspicion,” Commonwealth v. Watson, 430 Mass. 725, 729 (2000), and that “[t]he gravity of the crime and the present danger of the circumstances may be considered in the reasonable suspicion analysis,” Commonwealth v. Depina, 456 Mass. 238, 247 (2010), the trooper clearly had reasonable suspicion for the stop.

2007Commonwealth v. Roland R., 448 Mass. 278, 284-285 (2007), quoting Commonwealth v. Watson, 430 Mass. 725, 729 (2000).

2011See Commonwealth v. Landry, 438 Mass. 206, 210 (2002) ("Possessing a hypodermic needle is not necessarily a crime"; licensed physicians and private citizens "may lawfully possess hypodermic needles"); Commonwealth v. Alvarado, 423 Mass. 266, 270 (1996) ("carrying a concealed weapon is not, standing alone, an indication that criminal conduct has occurred or is contemplated"); Commonwealth v. Toole, 389 Mass. 159, 163 (1983) ("carrying a .45 caliber revolver is not necessarily a crime").

2025The reasonable suspicion analysis examines " the totality of the facts on which the seizure is based." Id., citing Commonwealth v. Meneus, 476 Mass. 231, 235 (2017).

2025Rather, as the Supreme Judicial Court acknowledged in Commonwealth v. Lopes, 455 Mass. 147, 155-156 (2009), quoting Commonwealth v. Lyons, 409 Mass. 16, 19 (1990), the Aguilar-Spinelli concepts of "basis of knowledge" and "reliab[ility]," to the extent they are relevant, are applied in a "less rigorous" manner in a reasonable suspicion analysis.

2024Id. at 156 , quoting Lyons, 409 Mass. at 19 .

2025See Westgate, 101 Mass. App. Ct. at 551.

2024I am bound by the decision in Westgate, and feel compelled to follow its dictates that under the collective knowledge doctrine I must “consider[ ] the contents of the 911 call,” even though those contents were not transmitted to any police officers in the field. 101 Mass. App. Ct. at 551 . -------------------------------------------- [16] Federal courts appear unwilling to consider information only known to a civilian 911 operator as part of the reasonable suspicion analysis.

2023In defining the reasonable suspicion test, the Court noted that "[a]nything less would invite intrusions upon constitutionally guaranteed rights based on nothing more substantial than inarticulate hunches" (emphasis added); and it remarked that a test based on good faith alone would subject the people to the discretion of the police, largely causing the constitutional protections to "evaporate." Id. at 22 .

2020The reasonable suspicion standard would require "specific and articulable facts" demonstrating reasonable suspicion that the targeted individual has committed, is committing, or will commit 4 a crime, see id. at 21-22 , and that there are reasonable grounds to believe that the data obtained from the query are relevant and material to an investigation of the crime.

2021This case is unlike Commonwealth v. Cheek, 413 Mass. 492, 493 (1992), relied on by the defendant, where the suspect was described only as "a [B]lack male with a black 3/4 length goose known as Angelo of the Humboldt group." Here, unlike in Cheek, police knew other distinguishing features, such as that the suspect "had facial hair," id. at 496 , [Note 13] and his approximate age, height, and build. [Note 14] Cf. id. (knowledge of suspect's height and weight could help support reasonable suspicion).

2000Although we have not applied exactly the same analysis as Federal courts, we have also allowed limited exceptions to the reasonable suspicion requirement where an intrusion is limited and serves a pressing public purpose. 3 In Commonwealth v. McGeoghegan, 389 Mass. 137, 143-145 (1983), we first indicated that sobriety checkpoints could be conducted in such a way as to comply with constitutional constraints under both the Federal and State constitutions.

Whitfield, 634 F.3d 741, 746 (3d Cir. 2010) ("It would make little sense to decline to apply the collective knowledge doctrine in a fast-paced, dynamic situation such as we have before us, in which the officers worked together as a unified and tight-knit team; indeed, it would be impractical to expect an officer in such a situation to communicate to the other officers every fact that could be pertinent in a subsequent reasonable suspicion analysis"); United States v. Nunez, 455 F.3d 1223, 1226 (11th Cir. 2006) (reasonable suspicion determined from "collective knowledge of
