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.

None

No punishment.
This is simply not true. Police may not keep you detained if they do not have probable cause or reasonable suspicion that you have committed a crime. However, in real life, they do this sometimes, even though it's been ruled unconstitutional.
They do occasionally face repercussions. Thousands of civil rights lawsuits are settled quietly around the country every year, and some go to court and establish precedents, such as Turner v. Driver.
They don't suffer consequences enough, though, and depend on citizens not knowing that what the police are doing is wrong. It's also difficult due to the "thin blue line" BS where cops are elevated above the rest of society.
They don't have to charge you, so they don't have to prove it.

The police themselves hardly ever face consequences; the settlements come from the taxpayer.
