When Hermiston police searched the apartment of a 20-year-old man arrested for vandalism they found a hand grenade.

The man also had an illegal knife (I don't have a photo, but I'd love to see what an illegal knife looks like) and is now charged as a felon in possession of a weapon.

But if a felon is caught vandalising property and in possession of a dangerous knife, the police can't be too careful, right?
