That's a far cry from this situation. There is no "judgment call" here: don't violently shove elderly people to the ground for no reason. If you accidentally do, help them up. If you pass by an elderly person lying on the ground and bleeding, check on them.
There's no "mistake" here.
I wasn't talking about this specific case though, not sure how you inferred that from my comment that shoving old man was a mistake .
I was talking about a hypothetical case where it was indeed a mistake.
If you're a passenger on a plane whose pilot is doing something unsafe, you'll probably never know, which is different from if you're a victim of abuse by police (because you'll directly experience the consequences individually directed to you). Nonetheless, the pilot's unsafe behavior also has a real potential to harm you, just in a way that doesn't feel intentional or personal, and in a way that's almost always invisible except in case of an after-the-fact investigation.
There are lots of ways that the analogy breaks down, but I see one where I disagree with you: policing does also have "lots of very complex and nuanced situations [...] that require judgment calls" alongside the situations that are best described as willful abuse and crime.
I completely agree, and I didn't mean to imply otherwise. I just meant to point out that this situation was not one of them.
The policemen attitude in the video is revolting
