Detroit At It Again.
Oops my bad! I got the wrong sample here.
I think I may have misidentified your suspect here.
I don't know what they were really saying there but Detroit's new Mayor has shut down the city's crime lab because it so error prone. People are depending on this for justice, to condemn the guilty and vindicate the innocent. Detroit cannot tolerate such an error rate. It appears that the bulk of the mistakes were in the ballistics lab.
When the crime lab is wrong a full 10% of the time, you wonder how they get anything done. An occasional mistake is a fact of life, but this is ridiculous. It's like a doctor misdiagnosing a disease; realistically it's going to happen from time to time, but when your wrong 10% of the time something is seriously wrong.
I don't like the idea of firing people, but heads had better roll here.
The lab employees will be re-assigned until the investigation is complete and they find out how it got so bad. With as much corruption as Detroit has, it would not totally shock me to discover that some of the mistakes were political favors, but that could not possibly account for all of the mistakes.
The problem was uncovered in April by a private investigator. For the time being, the tests will be conducted in State Police Labs which will slow things down considerably.
