You should first get a restraining order on the psychobitch, then you may try to sue her. Find out if a neighbour saw her do it, you need proof in order to win a case against her. Don't get revenge it will just escalate to something stupid. My first instinct would be to bash the bitches head into some concrete but you have to be smart and keep your cool. She will get what she deserves. What goes around comes around!!! Always remember that. If you start screwing around and getting revenge you will just get into more shit. Go after her legally and get that restraining order so if she sets foot on your property or near your car again she will be hauled off to jail and held accountable for her actions. And maybe, just maybe she will end up in a cell with a huge butch shemale named Bertha and she will be forced to perform sexual favours on the syphilitic, genital wart infested whore.
