State to state there is some variation in the use of deadly force. This instance, without a gate and/or No Trespassing sign, shooting into a car turning into a driveway appears to be stupidly criminal and in no way is sensible on its face.
Even without a gate and/or No Trespassing sign, the shooting would still be unjustified both by law and commonsense. Anyone who justifies this shooting is too stupid and irresponsible to have a firearm, simple as that. It’s because of idiots like this that we get gun control laws.
