Time v. Opportunity
...this would also seem to highlight that as a bad tactic.
Purses get grabbed. Autos get broken into, as do homes. 2 out of those 3 might not be good places to leave your firearm unattended. (OK 3 out of 3 are bad places to leave firearms unattended)
Given enough time your safe is not safe but a time delay tactic. Some bad guys might look in the kitchen pantry for valuables or hall linen closet. Maybe. Probably not much to pawn there tho'. Once they do find your gun safe (assuming you're not in the house when this occurs mind you) if they are determined enough and have some time to spare, it too, is toast.
But pros are pros, nothing is safe once they decide to gain possession.
A free people ought not only to be armed and disciplined, but they should have sufficient arms and ammunition to maintain a status of independence from any who might attempt to abuse them, which would include their own government." - George Washington, January 8, 1790, First State of the Union Address
