Subway’s New Security System

We can all agree at this point that Subway needs to increase it's security but this sounds, well...crazy!

Subway is rolling out their own synthetic DNA substance that will be located above the restaurants door.

Whenever there's a robbery at a Subway, an employee presses a button, and the stuff sprays all over the criminal as he leaves.

The DNA substance stays on a persons skin for up to seven weeks. You can not wash it off and it's invisible to the suspect.

According to ABC 6 - Knoxville, the substance will only show up under black light so the cops can check a suspect for it and prove he either was or wasn't the person who knocked off the Subway.  Each store has its own unique DNA, just to make sure there aren't any false positives.
