Well, being low paid law enforcement; heck yes I would pick that up.
First I would ask someone to get it for me: I mean you never know.
If that did not work, I general have a pair of latex gloves on me.
But even if I was not low paid; yes I would get it, thats just my nature, I can not pass up money.
Found some dumb Officers Army issued side arm in a port or jon at NTC. Yes I picked it up, yes I cleaned it, yes I heard about some dumb support officer loosing his weapon and troops doing hands across the desert. No I did not turn it in. I told my Team Leader, he said good job, nice find man. I found 22 weapons in my career, yes I kept every last one of them. Confiscated weapons, only got to keep the ones my Team Leader said was cool to keep.
Your not the first to get paid that way. Next time if you want to be funny, just wait until others come in and say he guys look, a penny, and then grab it and show everyone.
