yes. But there are still people that believe Elvis is alive. No matter the evidence, some people can't be convinced something has happen, if they don't want to believe in it.
Where do you draw the line?
In this case, 12 people of the jury thought he did it. Since I wasn't in the trial, and didn't see the evidence, I have no recourse but to believe that there was reason enough to convict him. This was not a racially charged situation, so it is hard to argue that the jury was biased, or anything like that.
Whilst not racially charged, as SwellJoe points out, Hans (and others) have personalities (aspergers??) so different from any member of the jury he may as well be totally foreign to them.
my gf has aspergers and although she acts strange she wouldn't go to the lengths that hans did. which is more than a little strange especially given the circumstances.
