They may confiscate your phone and record all data on it.

If it's a fresh wipe with a good passcode, and you keep it on airplane mode, you're probably fine.

Burner phone ... leave your main one at home ... ABSOLUTELY DO NOT BRING YOUR MAIN PHONE

Set up your burner phone with one or two accounts to things you might want to upload to ... encrypt as much as you can. Do not load all your social accounts ... only log into the bare minimum. If you are organized, log into temporary or fake or secondary accounts if you can.

Start the day without any prior history, photos or content on the phone and keep as few contacts as you can ... memorize numbers that are important to you.

Always be prepared to give up or lose your phone.

And as always ... SAFETY GLASSES .... bring a pair of industry rated CSA approved safety glasses (try to get a pair with a tint so you can pass them as sunglasses). Look for safety glasses with anything marked ANSI Z87+, sometimes written Z87.1+ (note the plus) rated or CSA Z94.3 rated are ensured to safely withstand a direct high energy strike.

.... additional things if you want to do more

Bring a small new blank paper note book you can keep in a pocket with a small pen or pencil ... you might be taking notes like license plates, name tags or names of people or places ... its always faster to just write something down than in taking a shaky photo or tapping away a note on an app

Wear a big scarf ... for guys or girls ... a scarf comes in handy for all kinds of emergencies including using it as something to cover your mouth, dress a wound, tie something or cover something up.

Wear a good pair of running shoes ... be prepared to run and be on your feet all day.

Bring a small backpack and bring a couple bottles of water and some energy bars ... keep it light because you'll be on your feet all day and if things go bad, you might be targeted if you have a large pack ... plus an empty pack can be used to carry things later if you need to.

Dress for the weather ... if its going to be hot, wear light clothing but if things go bad and you have to stay out over night or longer, bring a light jacket ... if rain is forecast within a day or two, bring a small poncho

Why do you need an ID? Leave it in your car if you're driving.

I don't think there's a single state that requires you to actually carry documentation.

Stop and identify statutes - Wikipedia

(en.wikipedia.org)

These are the states that require you to at least verbally state your name, and only if the officer has reasonable suspicion that you have or will commit a crime.

They can ask your name. You may not have to answer.

Research your state's law on this before you go. It's in the link.

Regardless of the law, you can be detained by law enforcement if you cannot prove who you say you are until you can prove it.

I've seen plenty of videos of cops holding a suspect down and forcing a fingerprint unlock...

So it should be safe in airplane mode, no? If I can trust my device, that is.

Use cash.

The powers that you are necessarily taking these precautions against are all funded by your taxes.

I learned this recently: if you have an iPhone, pressing the lock button five times rapidly will lock it so that you need to enter a passcode, not just FaceID. Useful if you think somebody might forcibly use your face to unlock it

Jesus Christ, this conversation is scary. I wish y’all good luck that none of these precautions are necessary.

As someone in a blue state where governance is sane, I’m “raw dogging it” (effing offensive slang term but now I’ve used it once in my life and can rest easy) and bringing my kids (teens). M also going to the local demonstration rather than go into the city for a big one - to some extent it’s a numbers game: ICE can’t raid them all and police aren’t legally allowed to help them

…. And hopefully my optimism is well founded

Edit: huge success! Entirely peaceful. While a few cops drove by, there was no police presence. Thousands of people of all ages lining both sides of main st, and three sides of our town common. Constant honking from supporters driving by. It was very inspirational. I’m proud of my fellow citizens and hope our voice for restoring sanity and democracy is heard.

For those pessimists,a bit more context why I was so optimistic….. a few years back, our mayor and police were participants in a local BLM rally. Also a big part of local outrage against fascism was a city counselor getting assaulted and arrested for videoing an illegal raid on one of his constituents.
