What if we take the word "auto" and change it to "home"? The logic and statement still remains true... there is no way to absolutely stop a thief.
My recommendation is to never leave any firearm in your home since there is no way to absolutely stop a thief who is after your stuff unless you catch them in the act.
Point being that in your home or your car, all you can do is take some steps to try to prevent theft, or at least make it more difficult. But if someone breaks into my home or my car and steals my firearm, I am still the victim of the crime and should not be punished for it.
We are not liable for a criminal breaking in and stealing a firearm out of our home or our vehicle at lest not in my state.
I just would not even leave one in a vehicle unless I am compelled to do so resulting from the federal government
not permitting me to carry it with me inside a post office.
I am not responsible for the federal government's decision
on that issue, I just have to obey their law. The safest place
for the gun is to be on me, but someone at the federal level
thinks it is safer for the gun to be locked inside my vehicle
than on me when I walk into a post office.
I do keep the best alarm systems on my vehicles and I would
protect my firearms in them if I were armed. When the federal
government chooses to force me to not carry into a place like
the post office I am left with the choice of just taking reasonable precautions which is a good car alarm system and
keeping any loss I might incur insured.
I think if I were a car thief or a gun thief, that's where I would
go to look for a car to steal, since lots of folks leave their vehicles unlocked.
One day I had a young black man very angrily denounce me
for locking my car door with my remote at a post office.
I learned that day that all I could do was call the police about
it since the post office did not own the street parking.
Of course I was unarmed at that point, so I could have been
carjacked, robbed of my car remote, lost my vehicle and my
gun, but I have insurance. What he does with the gun
afterwards is a matter for the police and the justice department.
I could suggest to them they change that law but I am not
going to hold my breath, because its not going to happen.
