Get rid of the bad apples for God's sake.
If Lanza had not killed himself he still would not have been found guilty and we would be at this exact same point in gun control discussions. We make far to many excuses for bad behavior. How many times have you seen news shows and tv shows about the perpetrator not being "bad" but just misunderstood, or bullied, or in the wrong place at the wrong time, etc etc? No one is responsible anymore. Unless you are a law abiding citizen and you break some arcane law or have a clip that is to big, then they throw the book at you. the penalties are fearsome only if you care about yourself and your reputation. The penalties must be more severe for the violent, ill, and just plain criminal element.
