biggest case in recent years was these kids in michigan who worked at this pizza shop, and an employee was brutally murdered while on the job. They blamed some other employe, then interiagated him for over 36 hours, police using all there tacktics (keep in mind, this is a basicly normal 18 year old kid) then after 36 hours straight, the kid signed a confession because the cop said that everything would be over, and he could go back home. He spent 90 days in jail until they found a person in kentucky area that was finally cought after several crime sprees. The person ammited to a muder and robbery in the same town, around the same time. Finally the realized that they had convicted the wrong guy.
