Some merchantmen have them:
A suspected pirate has been shot dead as private guards repelled an attack on a cargo ship off Somalia, in what may have been the first such incident.
The EU naval force (Navfor) says the suspect was found dead by a team from an EU warship which was responding to a distress call from the cargo ship.
Guards aboard the Panamanian-flagged MV Almezaan had returned fire after the ship was attacked, it added.
Six other suspected pirates were detained by a Spanish Navfor ship.
Probably won’t much change the dynamic, but taken as a whole, one less pirate in the world is not a bad thing.
