Quoting https://thenieveslawfirm.com/do-police-have-to-identify-them...:

You’re minding your own business when a police officer approaches you. They start asking questions, but something feels off. You ask for their name and badge number, but they refuse. What do you do?

As a citizen, you want to trust and cooperate with law enforcement, but you also have rights that must be protected. The question of whether police officers are legally required to identify themselves when asked is a complex one, with no easy answers.

In general, no, a police officer does not have to identify themselves even if you ask them—making it even more important to invoke your right to silence no matter who you think you’re talking to.

California Penal Code Section 830.10 states:

“Any uniformed peace officer shall wear a badge, nameplate, or other device which bears clearly on its face the identification number or name of the officer.”

However, there are a couple of key issues with this law that limit its effectiveness in ensuring police accountability:

    The law only applies to uniformed officers, meaning that plainclothes officers or those working undercover are not required to wear any identifying information.
    Even for uniformed officers, the law doesn’t explicitly require them to make their badge number or name easily visible or accessible to the public. An officer could potentially wear their identifying information in a manner that is obscured or difficult to read.

What about when your next door neighbor is walking down your street when an unmarked van pulls up and a bunch of masked men in plain clothes grab her off the street and throw her in the van? (Which literally is what is happening)

Are worried when they are arresting you and are masked and without ID?

Hiding their identity completely undermines accountability.

It's also an extremely glaring public safety risk to normalize people who refuse to identify themselves using force and guns to grab and pull people off the street with nothing more than a "trust me, bro".

Typically, you wouldn’t need to - they are supposed to have their names and ID’s on their badges.

And as long as you’re not actively interfering with something they are doing, yes you can and should be able to do exactly that.

Because you’re a member of the public, and you should be able to complain and if they are doing something bad, they should actually be held accountable to it.

Crazy eh?

ICE and the like know what they’re doing, and why.

Sorry but this is bootlicker logic.

Yes you should.
