I've heard a couple of news reports that suggested that simply because there were no criminal charges that means that the person arrested hadn't done anything wrong. And therefore the police had been heavy handed and had over reacted. So, if the police want to avoid that accusation they should charge everyone? The media pundits want people to have criminal records, even when there are better ways of dealing with them? It's a crazy old world when giving someone a break means you end up being castigated.
