Following these types of channels, we easily come to the conclusion that ICE is not a new phenomena in the USA, but just the regular type of law enforcement that just received "carte blanche" to act in the way they often do without punishment.
The kind of acts, lawful or not, performed without due process and correct procedure, seems to be a very common routine to law enforcement in the USA, and the courageous officers who refrain from doing, and protect population from the bad cops are a special type of law enforcement that has a human conscience to do the lawful thing, and in that, the right thing.
However, very few of these videos show good deescalation and the will of officers to not exert their authority when a situation in which they can presents itself.
Someone can ask: Ok, but this channels might filter for the worse interactions, as boring nice interactions may not be good for the channel. Is there a control?
Yes, there is.
In these "Auditors" channels, you see that even the population at large chooses to enter a confrontations over nothing, instead of going on with their days and simply be. Very few people are nice, and those are often the ones a lot of the USA population discriminate against for being "too nice".
In Brazil we have an old saying, that was not started here, for sure: "Honest people are never governed by dishonest people."
You will get the authorities, the politicians, and the celebrities, all the evident people shows a subset of the culture they were born in.
