I say we take our chances and risk some crackheads relative hiring a hit man to attempt to kill a citizen who lawfully dispatched some thug. Then said lawful citizen will have the opportunity to add another notch or two.
Besides, it should pretty much be open season on hired killers anyway. In fact it should be open season on anyone who advocates their employ.
Give you an idea how this happens ~ you go knock on a door at a house where you thought you had been invited for a Halloween party. The homeowner comes to the door and blows your brains out.
Frankly he should not be immune from civil suits in that case.
Just because you think were frightened doesn't justify an economically damaging or disastrous penalty on someone who makes a minor mistake ~ and knocks on the wrong door, got there on the wrong day, left his party mask on (thinking to surprise you), or thinking you weren't insane, or drunk, or on narcotics.
I'd suggest the Republicans who came up with the version they just pushed through the Virginia House go back and take a look at it and see if they've dealt with the "revenge" issue.
Time for the to think like "criminals" for a moment ~
