I have an errand to run at Beech Grove Firearms, across the street from the Vast FEMA Extermination Camp (*snicker*). If I don't make it back, send the internet commandos.
"zomg teh barb wire points inwards!!!!1!1!!one!"
(PS: If you really believe that the Amtrak facility in Beech Grove is a "FEMA Extermination Camp", you are obviously barely multicelled and dumber than jello. Grownups are chatting here, so please don't drool in the comments section.)
EDIT II: And can anyone guess why barbed wire points inward almost everywhere these days, including the Amtrak facility? Class? That's right. Lawyers. Because when Seth & Jared go to climb the fence so they can spray paint "Jared luvs Tifani 4evar" on the dining car, and the barbed wire is pointing out, if they try to climb over, they fall, break something, and then Mommy and Daddy sue the crap out of Amtrak, the fence maker, and whoever poured the concrete for the sidewalk. Whereas if it points inwards, they usually just give it up for a bad idea and climb back down, or get their Abercrombie & Fitch baggy drawers all snarled up in the barbed wire until the mall ninjas come out in the golf cart to help them down and call the police.
As anyone who's ever driven past a real jail or prison or maximum security site knows, nobody uses three strands of barbed wire if they're serious about keeping people out anyway. They use razor wire a la concertina.
