HARRISBURG — A fiery state House debate on a gun bill turned into a ugly shouting match on the floor Wednesday, that included expletives and a comment taken as a threatening racial epithet, according to lawmakers who witnessed the events. The tempers-flaring exchange came a day after two pieces of proposed gun regulation were voted down in the House by a 101-102 margin, with a third bill narrowly passing. Much of Wednesday’s debate dealt with the philosophical question of constitutional gun rights rather than the legal details of Steele’s bill. “Tensions are high in the building for an obvious number of reasons,” Topper said in a statement Wednesday afternoon.
