I work with "security officers" on the reg. These are guys who make extra on the side not being cops, working security for the network. And we have our laughs, and things are convivial, and then you say something vaguely controversial and it's like you flipped a goddamn switch. They're not your buddy the "security officer" hanging out on the couch anymore; they're the cop looking for a skull to crack. You can see it in their eyes, in their posture, and in the way their speech changes. When I was in the clubs we had security guards that were definitely headed for the force and we had security guards that were paying the bills. There was one I didn't get along with because he defaulted to skull-cracker. The last I heard he'd "had" to use his sidearm in the line of duty four times, killing three people.
