Won't bash you about leaving the gun in the unlocked trunk. It's already a dead horse.
Most police officers don't know anything about guns other than the ones with which they are trained or own personally. Even then, my next door neighbor, a police officer issued a Glock 22, a Remington 870, and an AR-15 carbine, asked for my help when he couldn't get his SiG 556 disassembled. After I got it apart (after reading the manual since I'd never seen one), I told him he needed to clean it. The bolt carrier and operating rod were stuck together. I had to bang the back of the upper receiver on the floor to get them to come apart after removing the operating handle.
My next door neighbor can be excused. He grew up in New York City and had no experience with guns before moving to Oklahoma. He was a school teacher before joining the police. Only after being trained on his issue weapons did he realize that guns are tools, really neat tools.
