Twice today I've had cases where I have witness evidence pointing to a suspect, backed with material evidence.. and then I accuse the person, and it's not them!
It is increadably aggrevating to have one piece of PE and one witness statement against a POI that won't give up an alibi. I tend to risk an accusation... and that's why I have two hits on my record that I can't pay off yet! Don't be like me, play safe! ;)
