No, or I would not be on FR.
siding with the violent felons of the world........
No again. You guys however are siding with a violent felon. Attempted murder with a car is no better than attempted murder with a gun. I do not support vigilantism. She made herself the judge, jury, and executioner. I do not nor will not laud such conduct. Because if we do, you may as well throw the Constitution out the window.
. . . of course, the fact that she knew the victim indicates that she may have been motivated by something other than defense of self or others, BUT if she's smart that's the story she'll tell in court.
IF the police bother to look for her. I have a feeling her description is on a tiny 3x5 card in the back of a locked filing cabinet behind the furnace in a closet in a basement with a sign on the door reading "BEWARE OF LEOPARD".
Come to think of it, she can turn the fact that she knew the victim around in her own favor -- she had no duty to flee in her car and leave her friend, the robbery victim, at the mercy of a man with a pistol (who actually fires said pistol during the contretemps).
