He never pulled and shot his weapon in 30 years of law enforcement -- so then how could that have been automatic???
Cops are required to train with their firearms. One of the oddities about habit was cops were getting shot by the bad guys because they stopped to pick up their brass before reloading in a gun fight. Turned out that cops were always required to do that at the range. Picking up brass as housekeeping on the range became a habit which got cops killed later.
