Phones should be turned off or left at home anyways when protesting. Here are my 10 commandments for engaging in protests:
1: never bring your wallet/ID. If you need to buy things, bring cash
2: either shut off your phone or leave it with your wallet. Recording police violence can be useful, in that case get the aclu app, a burner phone with the app, or an action camera
3: never speak to police under any circumstance
4: you can beat the charge but you can’t beat the ride
5: bring water, it’s more useful than for just drinking
6: bring hats, sunglasses, etc to avoid being identified by the state if it gets violent
7: wear good running shoes
8: know your rights, both federal and local, and when to use them
9: take out any contact lenses in case police use tear gas
10: stay aware of your surroundings; listen to picket line enforcers/community organizers
These are all fine in the US, but in other countries not carrying proof of identity can get you into some trouble, as can refusing to talk to the police. Know your local laws.
It is what people say about Germany but my teacher says that she didn’t have an id card for 10 years and only got one because of tour to a place organised by her university required to show id card to be put in their touring list. As far as her experience goes, no authority ever put her in trouble for not carrying an ID.
The same way that the police never put me in trouble for mu id card not having my address.
About not talking to the police, it is actually a right you have in Germany despite popular gossip saying otherwise.
The problem of not talking to the police is that the police can create reasons to put you in troubles for not doing so, as the police have the privilege of authority, power and legal/public trust.
But when questioned by the police, if it is worth, you have the right to have e lawer to answer it for you or to guide you on your answer according to laws.
This is scary because it could be exploited very easily by bad actors and is a huge invasion of privacy
