By the way...this actually happened. A cop lost his shit and screamed "SHOTS FIRED!" when an acorn fell near him. He started shooting all over the place in a suberb which caused another cop nearby to also start shooting at nothing.
Why do we train our cops to be so terrified of everything?
I think it might be hiring. I've got a relative who was too paranoid and antsy for the post office, but he's fit right in as a sheriff's deputy. I'm glad he found a place to belong.
