witch hunt or witch craft?

I recently watched a movie in my Global Studies class called "Paradise Lost" and its about three teenagers in West Memphis Arkansas being accused of murdering three 2nd graders. the police linked the murders to be satanic and blamed these boys who wore black and listened to heavy metal music and had black hair people who thought they were weird. Well in this small town of Arkansas they thought they had had the killers but they didn't have any evidence to link them to the murders and the tried them anyway because one boy named Jessie Misskelly was forced into a false confession he was interrogated for about 12 hours and the cop recorded 45 minutes of the confession. there people lie on the stand saying they heard these boys talking about the murders but the stories never lined up or made sense. Damien Elchols studied the wicka religion witch he praises the earth he was also studying to be a Catholic preacher but he was blamed and sentenced to death three times for killing those boys. the prosecutors scared the jury into thinking they did it without evidence and sentenced they all to prison for life. its just crazy to think that you could just point fingers at innocent people blame them and send them to prison without sufficient evidence to prove they did it.
