It's literally a fourth amendment right. I'm not cool with any of my rights being infringed upon. No one should be ok with this.

As an individual, its probably easier to just show ID, but as a society its a bad idea to let this become the norm. Because the next step is just checkpoints.

Very authoritarian. You shouldn't have to justify your existence, the government should be the ones with the burden to prove you did something wrong, you shouldn't need to prove your innocence.

…it soon became evident that this net was cast too wide for any private agency. Not merely was my own mail opened, but the mail of all my relatives and friends—people residing in places as far apart as California and Florida. I recall the bland smile of a government official to whom I complained about this matter: "If you have nothing to hide you have nothing to fear."

They know they're being racially profiled and didn't feel like playing along and making life easier for the cops.

As others have said we are not required to provide ID unless there is a cause. Stopping 2 people without stating why means no cause and they have the right to say no and it should end with ok have a nice day, but our rights are tested more and more. Some good news is its generally an easy case for a lawyer to pickup and win meaning they could get a payout from the city. The sad news is generally nothing will be done about the cops who abuse their job and cause the tax payers more money in lawsuits that should never happen.

When assessing the degree and quality of liberty in a country, one of the factors considered in academic political science is the requirement of personal identification by law enforcement. It [used] to be a trope of Hollywood cinema that takes place in the Eastern Bloc (Warsaw Pact countries) that ordinary citizens and obvious tourists were routinely harassed by law enforcement for their papers, a stark reminder that here in the states you can even cross state lines without identifying yourself.

It's getting more interesting as law enforcement is pre-emptively collecting biometric data on school kids and other vulnerable demographics.

Currently wending through state courts is the controversy of using biometric data to identify suspects, which may be regarded as an [unreasonable] search from which we (all, citizens or otherwise) are supposed to be protected, according to the fourth amendment to the Constitution of the United States.

In this specific incident, the NYPD is notoriously racist and aggressive, so this may be contempt of cop while black As the adage goes, you can beat the rap but you can't beat the ride. This assures these young men will have a bad week regardless of their guilt of any wrongdoing.

Are you required to always carry ID in your country?
