Isn't it fairly standard practice to separate children from their guardians when they are detained by law enforcement? We can of course have a discussion about whether this is warranted or not, I'm of the opinion that it isn't in the case of non violent offenses, but I would assume it happens fairly regularly to white people who are accused of breaking the law.

With regards to police violence, it definitely does disproportionately affect minorities, and in particular black men, but I feel in general the government is pretty good at turning a blind eye to police brutality and prosecutorial overreach even when it affects whites.
