cn and sv nailed it on the head.
In fact, if you're in a situation where someone breaks into your home and you live in an area where you're allowed to defend your home.. and use lethal force when you feel your life threatened.. You may still have to show or prove you weren't intentionally trying to kill them, only stop them. However, if they live, they will sue you and probably take everything you have. Its better to presume this might happen, than to presume it won't. Following that line of thinking... you can connect the dots yourself.
A few bad cops doesn't make them all bad. There are still a lot of good people out there. The real problem is that its the laws that empower them to justify shooting a dog, as mentioned above. The lawyers push for more laws because it makes them more money, and it makes for more lawyers. A make-work situation. And you are forced to hire lawyers because they created a virtual language that only they know, and not knowing it without one will be like plea-bargaining for a worse offense than one committed. Money money money. Its kinda like doctors handwriting, you have to be a doctor to be able to read it. Its got nothing to do with knowing what it means, because if you could read "sarcoidosis" then you can read about it yourself. If you ever got your hands on your doctors file on you, which you're not allowed to see (hrmm...), you wouldn't be able to read anything off of it to figure out what it says! Its like gibberish. I'm pretty sure there is a handwriting class somewhere along the way, right before you buy your doctorate, that indoctrinates your writing style. Another make-work club.
