Yup, gotta kill them. Dead men file no lawsuits. You do need to establish state of mind at the time of the incident. You have called the cops once. First step in the right direction. If it does ever go down, and you shoot someone in FL or anywhere when it is self defense, pull the trigger till it goes click. Empty the gun. One shot to the dome won't exactly be convincing to the cop that you were scared for your life. That looks calm cool and collected, not exactly the image you want to protray in a self defense siutation. Two center of mass to take care of business and then just empty the gun from there. Truly scared people don't shoot really well unless they have years of training. People with that kind of training aren't allowed to claim self defense when the other guy is dead and definitely aren't going to be scared of some punk.
