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.
Recently, in Minnesota, hundreds of people gathered in a protest on precisely this topic. They gathered to say (for their elected representatives and everyone else to hear) that they wanted a change to the laws and the system that permits police officers to kill people by kneeling on their neck when attempting to arrest them.
It was during this very protest that the CNN reporters were arrested.
So, as you can see, people are trying to solve that problem. They have been protesting loudly about it for the past decade (much longer, in truth, but there has been a renewed focus by the media within the past decade). And so far... well, you tell me whether you think it's working.
If the public so adamantly wants laws that elected representatives refuse to pass, then it seems that enabling direct democracy would be one solution to getting these laws passed.
