Thanks to the Admiral for backing my position on the zero-tolerance of terrorists and pirates.
Scum like the Hellfire Legion, who smuggle alien technology and possibly have a Nomad infestation must be destroyed if they enter Rheinland. We cannot afford to let the alien menace back into Rheinland... we've already lost many brave souls, as well as the respect of Sirius due to the Nomads.
However, I would suggest that demanding a scan from 'peaceful' terrorists and pirates is wise... this makes it easier to lure them into range of our guns. Dishonourable? Probably, but it's better than letting civilians end up on the receiving end of alien infiltrators. Honour matters little to the dead. I have used similar tricks and deceptions against pirates and smugglers to some success.
