"Particularly when almost certainly the gun was being carried in an illegal manner in the first place."<quoted text>
A person who has an IQ of 80 can FORESEE how his being neglectful of a deadly weapon could be used in a crime, and you have no way of knowing if your gun was not used in a robbery or even a homicide.
A firearm left unlocked in a car: the owner of the firearm is negligent.
Particularly when almost certainly the gun was being carried in an illegal manner in the first place.
It was probably being carried legally...then the individual had to make a stop at one of your established "gun free zones". In order to be legal, it had to be left behind in the car. Just like the Doctor in Texas that had to leave her gun in her car when she went to eat with her parents. She watched as her parents and many others were gunned down by a lunitic.
