This is what's happening around here with my friends in Law enforcement/Fire Medics;
Heard something interesting. It seems that if you're a heavy over weight minority female and the PD is about to cuff you, (around 2:30 in the morning) you faint. Yep, they don't know what it is but a lot of them will faint when the cuffs come out, and, and, in addition to that you just about can't bring them back around (unless the cops leaves - and they never do).
So when they faint the PD "must" call for the paramedics to come check them out. They have created a great field test to determine if they are faking it. (I'm serious this does take place - unofficially) Upon examining the individual, do stuff like; feel her forehead, gently squeeze her face, check her neck, carefully raise an eyelid - and jam your finger in her eye. If they levitate they are faking it. If they lay still, it's for real.
God I love creativity!!!
