As strange as it may sound to some (or many), I would say shoot them if and when found guilty beyond a shadow of a doubt. I base my comment first and foremost on my belief system, where no one is above the law, irrespective of who they are or how they may be related to you. End of story.
What I have said above is factual and can be checked up if one feels the need to do so. I don't expect people to like it or agree with it, but that's how reality is to some of us. I am not a judgmental person, I leave the judgment to our judiciary and do my best to follow the law of the land. If I screw up and end up breaking it for whatever reason, I would gladly hand myself in. I'm referring to major crimes here such as (for example) someone sexually molesting one of my daughters and the like. If for whatever reason I could not hold my temper and killed the culprit, then I would gladly go to jail for it. That's what I'm talking about when I say no one (not even I) is above the law, period!
