The MarkPet – LT. [Babel]. Japanese toy maker Sheriff appears to have moved into the security business with what looks to be an indelible paint ball gun, which you use to tag criminals on sight. Babel willing, it’s apparently designed for small store owners, security guards and the like (hence the photo of a pretty young lady eh?).

Fire paint ball at thief as he leaves scene, then catch him at will (’cause he can’t scrub the paint off skin and bone, and a part of the formula is invisible anyway). I think it also has some way of alerting the security forces when it’s fired too, maybe…
