Well like I said I'm not from the US and have no answers to a system that seems completely and obviously open to abuse. I'm always puzzled why it's the way it is in the US, the whole justice system seems like a farce especially the way the courts work.
I'm all from transparency, not only does it keep the cops right but it also means cops are safe from fabricated complaints they are subject to. I just find some of the ideas here about how to do this ridiculous from a reality perspective. And to suggest that the police should be presumed guilty it actually worse than ridiculous.
Why is it hateful to the police to actually ask for their interactions? As the modern authoritarian state asks its citizens, what do you have to hide?
