The decision to bust down a door of a home is one of the most difficult for police officers to make, second only to deadly force, experts say. "It's a very difficult call," said Charles Rogovin, who specializes in criminal justice as professor emeritus at Temple's Beasley School of Law. "Police officers shouldn't break into people's homes, but if there's suspicion of someone in imminent harm, or if criminal conduct could be taking place, it's appropriate for them to break in." When a Daily News reporter described the circumstances of a recent Philadelphia case, Rogovin said that the officers should have broken through the front door.
