..........If you want to compare an action to a penalty I would look toward the person with a vicious dog that posts a "beware of dog" sign - Case built that they knew the dog was dangerous. Think about the T-shirts you wear, bumper stickers you have on your vehicle, signs on your property, or things you post on social media that talk about property protected by Smith & Wesson, trespassers being shot and and survivors being shot again, nothing in this house (or car) is worth your life, etc.
Or in today's world, the mere fact you own, and are, "into guns", (many), can be shaped into something that can ruin your life both legally and financially. Remember, in the eyes of most hard core liberals, if you own guns and are in defense of the Second Amendment, that alone makes you an enemy worth going after. Not the guy you protected yourself against. You are in fact the, "gun nut". This mindset is increasing every day as the liberal anti gun crowd continues to lose ground. Just like in politics, the more they lose, the meaner and nastier they get.
A person who owns a large collection of weapons, and ammunition to go with it, is going to have a hard time if they're faced with a courtroom full of liberals, and a liberal prosecutor, judge, jury, and police department. There are many municipalities like this that are stacked against the conservative gun owner today. In fact, most large cities, (where a self defense shooting is most likely to occur), have these type of anti gun political people in place to crucify you.
