South Boston residents participating in bizarre local custom—a keg party on St. Patrick’s Day—draw the ire of a neighbor, who summons police. The police suspect underage drinking and enter the apartment through an open door. (Officers say their knocks were drowned out by the loud music.) Jury: That is not unlawful entry. District court: No, it is. Three officers must pay $1 each. First Circuit: Nope. Qualified immunity.
