40SW :
1 - Absolutly, the law is clear. Auto defense definition is your answer must be egal level of attaque level. If your agressor carry an edge weapon and you shoot him. You are a killer.
Of course sometime the judgement are not so ... strict. You are not a killer, you were at at home and the personn shoot was agressive, etc. etc.
It's clear you will have many problem. Like probably loose your legal possess weapons autorisation.
2 - Yes, it's a recommandation. You are not obliged. But the law say it's better to store the weapon and ammo's in two differents rooms or two different safe.
3 - Concealed carry is completly illegal. Carry a gun is illegal. If you have a police patrol controle, you must explain from where you come from and where you go with your weapon (ex : My house => to my usual shooting range, or an other shooting range for a contest). Alway the gun in a bag or a suit-case. NEVER in holster.
4 - Dont try to understand somethink stupid my friend
The only think clear for criminals working here is that it's an easy job, nobody have gun, nobody are dangerous.
5 - Yes, yes. The problem is that we are in a defensive position.
In our constitution, the citizen could have guns. But it's not an important point because we never have a system like your "minute men" or the switzerland constitution (every citizen become a soldier in case of war).
We have no risk if we dont have any big troubl with authorised weapons. At the first massacre perpetrate like incident in some american campus we will loose our gun. It's sure.
We have dodge a law for ban guns after a problem like this in the NANTERRE townhall. it's clear we have not loose our gun this time but the bullet miss the mark but not far.
