Almost never. I myself have only seen two videos where this has been the case, out of hundreds!
Police racism and violence is an issue, but it becomes egregious when the rest of the police force just stands by.
Are there any videos or stories at all over the past few days?
There have been reports in some cities of the actual good cops here and there taking part in the protests and actually looking like they want to improve things in their communities, but I haven't heard of anything where the police have intervened on cops that were escalating violence and brutalizing protesters.
It would be a pretty big turning point in the protests if this is actually happening
I cannot believe how far people will go seeing what they want to see.
On the whole, the cops have been insanely brutal.
You are saying "there exist police departments which are friendly with the protesters".
The thread you are replying to isn't talking about protests; it's discussing the absence of evidence where police officers actively intervened and stopped the excessive use of force by a fellow officer.
In the USA, a civilian doesn't have the right to defend themselves from an officer under any circumstances in most states. A very few states allow you to shoot to defend yourself (even from officers who don't present themselves as officers) under very narrow circumstances. Any way you cut it, police are given benefit of the doubt when interacting with suspects but the cheaper internet-connected cameras get, the more evidence that we should probably revisit that long-held doctrine.
Yeah but that only happened after the crowd was screaming at them to take their knee off. I doubt that would have happened if it weren't for the protestors and the optics of doing literally exactly what kicked off this latest protest to begin with. If those cops were alone and making that arrest a month ago I highly doubt the other cop would have stepped in to move his knee.
