I found him a good advocate of "don't talk to police", a lot of things he describes as standard police practice I would have hoped are illegal, and probably are in some EU countries (police can lie in interview??)
Both are equally stupid, but in different ways
It is possible that European police is more racist than US police, yes, but that wasn't what we were talking about. I'm pretty sure that US police is more violent against white people than European police is against gypsies, meaning that even with the racism European police is still much better.
Just looking at Western Europe (arbitrarily defined, granted, and leaving out some really small countries) in the list at https://en.wikipedia.org/wiki/List_of_countries_and_dependen..., the US has fewer police per capita than (in increasing per-capita order) Ireland, the Netherlands, Luxembourg, Austria, Scotland, Belgium, Germany, France, Portugal, Italy, Spain. More police than (in decreasing per-capita order) England+Wales, Switzerland, Sweden, Denmark, Iceland, Norway.
The US has about 25% more police per capita than Norway. Germany has 63% more police per capita than the US does.
That is not to say that we don't have problems with police brutality or cover-ups here, they are just less deadly usually.
It's pretty weak evidence, as the officer in the video is talking about violence during interview, not about killing civilians and I'll agree that these are different things. But it's more than enough to make me skeptical that you should be grateful that you're being interrogated by an american officer rather than an european one...
Very anecdotally, I've watched/read a lot of american news during the elections and the idea that they are "more robust" or more impartial than european news makes me chuckle (at least western europe as it's what I know, and not pretending that our journalism is laudable either)
One basic interrogation technique involves lying to you about what you're suspected of. The interrogator might accuse you of something they KNOW you didn't do. He then notes your reaction.... typically you will be outraged and confused.
Later when he accuses you of other crimes, he studies your reaction and compares it to the earlier reaction. He already knows what you look like when you truthfully deny a crime. Is your denial different this time? Yes? Then that gives him a hint that his current accusation might be accurate.
