Here’s a sobering article about the field test kits that police use to test for cocaine and meth. They have a high false positive rate. That means that people are getting arrested and taking plea deals on drug charges when they do not possess any drugs. Innocent people are going to jail because of a known lab error. If this does not make you angry, why not?
To be clear: police and prosecutors are arresting prosecuting and jailing innocent people on the basis of field testing kits that they know give false positive results. Just another bit of evidence that the drug war is failing.
