This is extremely disturbing, and further evidence that the U.S. is a police state. I've never felt more ashamed of my country.
Cops can hold you for some amount of time, generally around 24 hours without cause.
> What are the repercussions for these officers for falsely arresting people?
None
> Do they suffer any consequences, or do they suffer no punishment for this injustice?
No punishment.
At this point I'm basically waiting for a politician to adopt "soft on crime" as a campaign slogan and rebrand it as a rehabilitation program where you turn drug dealers into docile flower shop owners as opposed to opponents who "make crime tough" by sending people to "crime school" prisons and turning them into hardened career criminals with switchblades and facial tattoos.
The real problem is the same as it is in general -- special interest groups (in this case police and prison guard unions and private prison companies) are the ones who spend the most effort lobbying on the issue. It also doesn't help at all when we disenfranchise "convicts" because we're then disenfranchising the victims of the system whenever it makes a mistake (which is often).
