If you’re going somewhere where you think you might be at risk, IMHO, it’s probably just easier to turn your phone off. Android and iOS both require a non-biometric passcode after boot.
Or, if you want to keep your phone on, enable lockdown mode on Android, or tap power 5 times on iOS to require a non-biometric password at the next unlock.
It’s never a good idea to bring your phone with you. It can be used, even while powered off, to track and surveil you. The BLM protests were just the tip of the iceberg. The apps you have on your phone track you. The government is buying that tracking data. Your phone is a massive privacy weak point. It’s basically a bug you carry on you willingly. It’s not safe. Period.
Leave your phone at home. It’s not worth it. It may not bite you in the ass the day of, but could very easily come back to haunt you after they investigate, in case anything goes “wrong” in their eyes. It’s just not worth it.
IMHO, as someone that works in security / privacy, I tend not to view it as a binary thing. It depends on where you live, what you’re protesting, what you look like, who you are, etc.
Are you in Russia or China and are protesting the government? Yeah, I might leave that thing at home. Are you a white lady in San Francisco marching with a pink knit cat hat during brunch hours, then you’re probably well on the other side of the risk spectrum. You might actually be introducing more risk by having less immediate access to communication or a camera.

How? The only legit thing I can think of is if they are tracking you anyway, and then they see your phone is turned off, they might try to claim that you must be up to something. But they won’t be able to track it while it’s off.
That’s not quite how it works, though. These devices are basically mini computers now, there’s a limit to what they can do without fully booting. Devices that are plugged into the wall might be likely to retain some power-draining function while plugged in, but there’s only so much you can do on a trickle charge while a phone is powered off.
They’re still running in low power mode and can wakeup from the network so they can absolutelly be made to “boot up” without turning the screen on and you being aware of it.
This is not like a bloody PC were the lights turn on and you can hear the fans when the thing starts, it’s a machine with a low power mode in which it can already do a lot and which can be brought to a high power mode if needed without there being any visible or audible side-effects to alert the user.
Unless you completelly cut it off from power (by taking the battery out, which you can’t in most modern smartphones) that smartphone with the lights off, the screen off and making no sound at all can just as easilly be in low power mode waiting for you to press the On button, as it can be in full power mode with a mobile network connection active, accessing the microphone and the GPS microchip and sending that data out, and both will look exactly the same from the outside.
I think the fact that we are able to record everything that happens and automatically upload it seriously outweighs what you are saying.
The only reason cops get in trouble is only because people are filming. If it’s not caught on camera, it didn’t happen in the eyes of the law if it’s just our word against a cops.
