DNA TAGS shot by a gun are used by police to mark rioters. “Selectamark (what a name) also makes DNA grease, gel and spray to tag personal belongings or other items. It could conceivably be used to tag money in a bank heist, for instance–instead of a lot of ink exploding in a bag, the would-be robbers would get DNA all over themselves. If it lands on clothing, it won’t do the authorities any good, but if the pellets land on skin, their DNA mark will stay there for up to two weeks, according to the company.”
