People have noticed that the Capitol police were very gentle with the insurrectionists, and contrasted this with the violence of thugs in many cities towards peaceful protesters for Black Lives Matter and other progressive causes.

That the Capitol police restrained their violence was a good thing, and I think that helped some Republican leaders to withdraw their support from the wrecker. What was not good is that thugs did not extend the same respect and decency towards progressive protesters.

Why this difference? I think the Capitol police have been trained in how to deal with protesters with restraint and respecting their rights. They expect protests and expect journalists to be watching.

By contrast, the thug departments of cities vary. Some of them have a culture of violence toward progressives and especially blacks.

As has been pointed out, most thugs are right-wing and have cheered on right-wing counterprotesters even when those are killing Black Lives Matter protesters. I saw a rumor that some even took selfies with the insurrectionists at the Capitol.
