Too Many Mistakes
The police simply made too many mistakes. I will take into consideration the time period and the limited technology but still beyond that, the police really messed up the case. The newspapers/media should not have found out intimate details of the investigation. The police force should have known the area they were patrolling much better. Washing away/erasing vital evidence to the case is inexcusable. With the contradictory police reports, and lack of communication, the Metropolitan Police force might as well be called FEMA.
