This is probably bad advice but I'm going to throw it out there and hope someone with more legal knowledge will comment on it. A friend once admitted they keep a gun hidden in their house for self defense, but they didn't say if it was registered or not. I asked them if it wasn't, what was the logic behind that. He explained, and I think Bajo_Cero once said something similar, that if an intruder comes into your house you can shoot him if he shoots first and you're guilty depending on what time of day, and if he shoots first or if you do. It's a complicated law and I haven't read it. The point is, it's not like Texas where can own and carry a gun and if someone trespasses on your property and threatens you, you're have the legal right to defend yourself. Not so in Buenos Aires, the land of the Bermuda Triangle, where people choose not to work and get paid and thieves are rewarded sometimes with subsidies upon being released from prison. Back to the story. My friend said that it's more convenient to have an unregistered gun in your house in case you do have to shoot an intruder that enters your house because then you can claim that the gun you used was the intruder's, not your own.
