I can see why it isn't a cut and dry case then. That is something that would be difficult to prove yet easy to accuse for doing. However, if there was a police car driving around so erratically that it would cause the guy to break his neck and die, I would think that somebody would have seen it and reported it.
Yes, legal mumbo jumbo, we get it. Outside of said legal mumbo jumbo, how is being not guilty of something different from being innocent of something? Ya, you can say that they might not be innocent of something they did, but then again that would be the same as not being 'not guilty' of something they did. Being found not guilty and being found innocent, unless the law just establishes different definitions for both of those words just to confuse people, I see no problem just saying he was found innocent.
When the only legal trials ever in the news are those of cops (remember when it used to be kidnappers?) because half the nation wants them convicted regardless of the evidence, then you aren't going to get a very good idea of exactly how many people are getting off because of 'too little evidence'.
