People v.

2 sentences1991Defendant correctly notes that the probable cause test is a compromise for accommodating the often opposing interests of privacy and law enforcement and that “there is good reason for striking the compromise somewhat on the side of privacy where it is uncertain whether any crime has occurred.” (People v. Reynolds (1983), 94 Ill. 2d 160, 166 , 445 N.E.2d 766 .) In striking this balance, however, courts are also sensitive to the fact that policemen must often make the decision to arrest under ambiguous circumstances. 1991Defendant correctly notes that the probable cause test is a compromise for accommodating the often opposing interests of privacy and law enforcement and that “there is good reason for striking the compromise somewhat on the side of privacy where it is uncertain whether any crime has occurred.” (People v.
