Hm, same difference, BlueFlames. Besides, piracy is a symptom of an issue in an area. You should focus on why these people turn to piracy instead of just killing the ones you catch.
That being said, I imagine all the pirates understand that if they get caught there's a good chance they'll get killed - the Russians, for instance, set them adrift with no food and no water (they of course later turned up dead). I could see an argument for doing that and giving them one round for each person.
Thievery, should it occur, should be brash, bold, and loud. Thieves should have enough of a respect so that they don't try to hide what they do. The worst thief is not the one who attacks you in the middle of a wide open area, and makes clear their intentions. The worst thief is the one who slides up next to you when you're weakest, still whispering promises of assistance and friendship as they slide the knife into your back.
I have more respect for the Somali pirates than I have for many of the people in power in our country.
