Forget about safes. If you want one buy one and get it installed or leave your valuables in your own country. A friend of mine has a cousin who is a wealthy judge.. He has major security, a body guard ,a safe, cameras etc..
A couple of guys entered the house disconnect the security sytem and proceeded to torture the wife to make her give the combination of the safe. The judge got lose grabbed a gun and shot one of the guys, the other one ran away. The wife is in the hospital and they moved out , the house is for sale.
Do you have valuables that you would be tortured or give up your life for?
That happened in a nice section of Guadalajara
