That is the way most laws are designed. Not if someone hits you once you get to shoot them. You can disagree with that, but that is how many laws are designed, with levels of progression in violence in mind. Having seen the photos now though, I can understand the progression here, and the pictures do not jive with the tv news story at all.
I don't think people should face large periods of incarceration for theft, no. If some 20 year old steals your TV, he should not spend 10 years locked up, with the general public paying for his care for a decade. He should be given an appropriate sentence and should be able to do restorative justice, where he can pay back the person or company whose TV he stole. Who wants to pay millions of dollars for some asshole who has stolen a 300 dollar tv??? it doesn't make sense.
I dont stab anyone, I see a lot of this sort of violence at work. And the goal is always to take people out of the system and make them productive tax paying citizens who contribute to society.
Im out, have to go eat before work. Good chat though, I like to hear opposing points of view, It is ignorant to think that my opinions are always right, and I respect your views, the ones that I agree with and the ones that I don't.

I agree that it is ignorant to think other people do not have valid opinions. However, I do think the U.S. legal analysis you have given isn't entirely correct. For example, the part I made bold is simply incorrect. You cannot
usually shot someone for merely punching you once in the face. You can defend yourself with deadly force if you reasonably believe that deadly force is being used against you. This is a very logical law and I would be nervous to live in a country that did not allow this.
Regarding theft, it depends in my personal opinion. If you commit home invasions, you should be locked up for 20 years or more. If you break a window of a store late at night and steal a t.v....eh, I personally don't think that is worth 20 years.
