When someone is investigated over sexual abuse, and then charged with 12 counts of sexual assault, and the whole thing goes to trial, none of us should be terribly surprised when that person is found guilty. After all, the CPS don't normally drag completely innocent people of the street, kicking and screaming, and then charge them at random, famous cases of miscarriages of justice aside.
It is often said everyone is innocent until proved guilty but if they weren't strongly suspected of guilt in the first place, most of them wouldn't be on trial at all.
What people can't always understand is that when someone is investigated for months and sometimes for years, and the resultant court case goes on for months, but still that person is found not guilty. That for me is the more mystifying aspect of our law.
