This same reasoning (that detergent and other ubiquitous household substances shine in UV) explains why the police might not use a fluorescent marker (leaving aside the question of why you'd dump it on a *legal* assembly), but I am sure this rumor will now be ineradicable

I can think of many other ways to identify protesters. Also why? This whole thing makes no sense to me—But it’s an indication of how the lack of trust is manifesting itself. I was at the rally. Quite uneventful and probably not a high priority for the police.

Also there are products for UV-marking in significant quantities (https://gmktp.co.uk/product/total-ir …)...

Yeah, which probably goes quite a way to explain why I've never seen it used in that role before. In the past few days HKPF have seemed pretty desperate to detain people without needing to front them during a protest, and crying 'unlawful assembly' for not much at all. We'll see!

Also as a note I didn't mention anything about water cannons in the question, just about if it's consistent with from a helicopter.
