My first shooting call as a cop started with me stopping a car full of migrant workers. All occupants had been shot by their cousin/brother/friend after a dispute over cards. The driver of the car kicked the party off when he took a 124 grain 9mm slug to the face from across the card table. He was the only one in a physical condition that left him able to drive.
Ballistic data and testing can tell us a lot about bullets, but at the end of the day, bullets do weird shit when they hit people, and people do some weird shit when they get shot. That’s just the way it is.
