Why are trials so highly publicized? Is it because people care? I don't. I don't want to know what this person did to that person or what happens to them. it's none of my concern. Sure it's fun to watch an idiot get what's coming to them, but does it have to be everywhere in the news?
They're an obedience lesson. "They" want you to see what will happen to you when you break their rules. If you are constantly inundated with examples you will be less likely to commit crime.
Next time you see a trial on TV, just watch something else... or better yet, get away from that TV and do something you actually enjoy.
