Can a cop pull you over walking home asking why you are out so late?

That's when the policemen spotted me: I was so tired I was unable to park where I found a spot, and just drove to the next one I found. When I left my car, they pulled me over and asked me a bunch of questions (the usual ones, like where I was going, where I was earlier, etc).

Sure they can. It happened to me a few years ago.

I told them I was in the office. They asked if I'd been drinking. I told them I was just too tired to park properly and wanted to go to bed. They kept asking dumb questions about my job (I was so tired I’m pretty sure I was really confusing), so they gave me a breathalyzer test, and then let me go once they understood they were just bothering a poor person working too many hours.

When Trump blames DEI, isn't he just saying "it must be because there's black or brown people involved"?

I was polite throughout the whole interaction, there wasn't much they could do. They weren't nice until it was clear I was just tired and not DUI, but that makes some sense.

I was going back home from my office, around 3 or 4 am. Huge project to hand in, I just kept on going until I had it finished and polished, and when I finally managed to finish I drove back and started looking for a parking spot.

Uhm, just as a note: Europe, not US.

Why wasn't Queen as successful in America as in other countries? Then, after Radio Ga Ga, they couldn't even get into the top 40 in America even when these songs were top 10 hits everywhere else in the world.
