Pennsylvania police officers no longer need a warrant to search a citizen's vehicle, according to a recent state Supreme Court opinion. The high court's opinion, released Tuesday, is being called a drastic change in citizens' rights and police powers. Previously, citizens could refuse an officer's request to search a vehicle. In most cases, the officer would then need a warrant — signed by a judge — to conduct the search.That's no longer the case, according to the opinion written by Supreme Court Justice Seamus McCaffery. The ruling, passed on a 4-2 vote, was made in regard to an appeal from a 2010 vehicle stop in Philadelphia.
