The man doing the shooting is a murderer. And it is very possible, based on reports that the authorities had been called in the past, that the dead teen was committed to making the man's life miserable.

Your first statement is true.

Your second statement is not necessarily accurate. Some people call the cops when it is not justified. Generally the cops know exactly who these people are. As do the other neighbors.

And the liberal establishment will have a great time permitting some family to sue you because their drunken teenager hits it and suffers more damage because you decided to protect your property.

Possible in many cases. As I live on the end of a cul de sac, it's pretty tough for somebody to have enough speed up to kill themselves when they ram my mailbox.

Just enough to mess up their car. :)
