gignerli,
I would like you to find and post these laws of which you speak.
Also the individual killed, did they get a bit too far with the person he was fooling? This is in no way a justification, the killer should be offed in my book, just an extreme act of cowardice. But if the victim was leading the guy on (who was no doubt horney), the victim was playing with a loaded gun pointed at his head.
There are Laws in France that prohibit women from wearing pants. It is also ignored as the stupid law it is.
