Is that bad?

Okay, I have a feeling this post is going to be a little long, so I will try to keep it as short as possible.
When I was a kid my dad had a 38 pistol. One day he told me why he bought it. He worked for an oil company in Duchesne, Utah. At the time there was an ex-con also working there. He had been convicted of Attempted Murder. I guess he had gotten mad at someone, and came up behind them and hit him over the head with a brick.
Well apparently this guy did not like my Dad, and let him know it. One day he told him that he better watch his back, because one day was going to hit him over the head. My dad believe him because he had done it before, and looked very serious when he said it. So after work that day my dad went out and bought a the 38 revolver. Then next day with the pistol strapped to his belt he walked up to the man and told him that if he hits him with a brick, he better make sure he is dead, because if he wasn’t he would come after him.
I think we let too many violent criminals get away with too many things. They get off because of the way evidence was collected, even thought the evidence clearly proves their guilt, or they get sent to jail for too short of a time compared to their crimes, then they get out on parole after serving only half their time. I think people can change, and sometimes they do. But the majority of these people know they are doing wrong when they are doing it, and most of them don’t care. Because of that I think most of them will do it again.
Take all the recent school shootings for example. Instead of surrounding the school and negotiating with them, just take the guy out. If he dies, at least hit was him not some kid. If someone rapes someone, cut is penis off, and I guarantee he will never do it again. If someone breaks into your house, don’t wait around to see if he is their just to steel you DVD player, or if he is there to harm your family. Assume there is a threat to your family and protect them.
I think if there were less tolerance for these kinds of crimes there would be a lot less of them. If they new that if they break into someone’s house they may not walk out again, if they take hostages the only negotiating will be between the two snipers about which one has the best shot, and if they have to sexually assult someone to feel like a man, everything man about them will be taken away, maybe they would reconsider their stupid ideas.
I hope this does not sound too harsh, maybe to some extent it is, but what I am trying to say is that we need to defend the victoms not the criminals, we need to protect our rights to live, and those of our families, we need to stop letting people get away with their crimes. We need to let them know we are not afraid to defend ourselves, that even though maybe not literally, we have our guns strapped to out belts and will use them to protect ourselves if we need to.
