@user3867599 I honestly don't know if what I'm about to say is a valid thing in the current situation
I was lucky enough to do some work in the US. I always carried identification with me but I would have done that in any country that's not mine. I do actually carry my driving license with me all the time here, even though I don't drive anymore.
I am not white, (I'm often mistaken for mixed race although I'm actually not) and the first few times I went there for work, I never thought about the colour of my skin.
I did think about it later when all the race stuff seemed to really take off - I mean, suddenly race baiters and Grifters began making a lot of money out of it.
It was a lovely place to work and to just be in generally.
I did see a couple of places being raided by immigration enforcement in NYC in the 2000s and I just walked past - as I would do in the UK. There's a business that's been closed in my local High Street and we are fairly sure that that's the reason why it was closed though there doesn't seem to be much information publicly available. They were surrounded by police and closed very suddenly. There were customers inside at the time.
My expereince in the US was pre-lockdown so wearing a suit for work was pretty normal and I probably just looked like a regular person going to work or being on a lunch break.
It wasn't something I thought about.
I have expressed puzzlement on here about the current situation because there seems to be either a lot of misinformation going round, or things have changed so much in the last 10 years, that my opinion and experience is invalid. It may well be - 10 years is a huge amount of time in terms of political and societal change.
I hope your DC enjoys America. I would certainly have gone back for a visit by now if not for elderly parent issues. I have never felt anything other than 100% welcome there.
editing to add - sorry MN is loading really slowly and I can't see all the posts in one go - if he wants to protest, he runs a very different risk than he runs in this country.
Law-enforcement carry guns in the US. It would not occur to me to interfere with law-enforcement in the US - ever.
I suppose the only thing you can tell him is to think very carefully about where he's getting his information. There is a shocking clip, which appears to be correct, with Renée's wife saying what sounds like "Why do they have real bullets?"
I'm baffled by this. Why would they not have real bullets? I just assume any law enforcement person I come across in the US is armed, including the ones that just say hello, good morning, etc when you're walking out of your hotel. Which I find they did quite a lot. It was all fine with me.
