DNA spray security system makes U.S. debut in Knoxville--in a Subway Sandwich shop.
This is some F'ed up shit.
KNOXVILLE, Tenn. (WVLT) -- Crooks in Knoxville may get a bit of a surprise the next time they try to rob a Subway in West Knoxville. The store is the first in the nation to get new technology that sprays the bad guys with DNA as they run out the door.
The technology has been successful in at least 30 countries for the past decade.
Monday it was installed in the Knoxville Subway on Sutherland Avenue and will be the first time it's been seen and tried in the U.S..
Quite a difference scene than a few months ago when that Subway was robbed by three men with guns in January. Now, they're taking steps to make sure that doesn't happen again.
"If a robber comes in and robs the place, the system gets activated and on his way out he will get marked with artificial DNA," Johan Larsen told Local 8 News. He's the senior vice president of CSI Protect.
The spray can only be seen with UV light and can stay on the suspect for up to 7 weeks.
"Another tool to get the bad guys," says Deputy Chief of Police, Gary Holliday.

That sounds about like something they'd come up with. No chance for anything to go wrong. 
Actually, maybe they'd have handheld units and the questioning rooms could be outfitted with a fixture. I have a really good handheld LED one, 24 LEDs, only about 5" long. We bought it for our bedroom carpet. Couldn't figure out where we missed shampooing it after the dog had an accident on it.
