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

No punishment.
Obviously cops only act in good faith, so any restrictions on them are restrictions on getting criminals off the street. </s>
