The justice system works most effectively when the actual criminals, are caught. As much man power as law enforcement enlists, humans sometimes just can’t fulfill the duties needed to apprehend suspects. The British Transport Police recently enlisted the aide of a $60,000 German-made UAV Microdrone to help patrol the British railways from metal thieves. Though thinking that an aerial Microdrone wasn’t enough of a surveillance deterrent, the Brits have mounted a special squirt gun on top of the robot which sprays the assailant with SmartWater, a liquid which helps the track the suspects in question.
