Police officers are violating the Fourth Amendment rights of people stopped on suspicion of trespass as they walk into and out of privately owned buildings that participate in a Bronx anti-crime program, a federal judge ruled yesterday.

Southern District Judge Shira Scheindlin (See Profile) issued a preliminary injunction ordering police “immediately to cease performing trespass stops” without reasonable suspicion of actual trespass at thousands of buildings whose owners have given police permission to patrol their property pursuant to the Trespass Affidavit Program, or TAP.
