Riots are a tough nut for law enforcement in part because of the sheer number of people involved--it’s impossible to stop and arrest every person involved in a skirmish. That’s why cops have some pretty high-tech methods for catching suspects, from facial recognition software to debilitating sonic cannons. But none is as bizarre as this new DNA gun from a UK security firm.
The SelectaDNA High Velocity System works like it sounds--it shoots people with pellets containing a unique DNA fingerprint. Unlike rubber-pellet guns, Tasers or tear gas canisters, the technology does not deter or disable the suspect--he or she can get away seemingly unscathed. But later, authorities can track down the suspect and arrest him or her “at a less confrontational time for officers,” according to the company. Portable readers equipped with ultraviolet light scanners would be able to verify the synthetic DNA.
