It seems to be a largely American thing to think the phrase is bad (reasonably so, given how it has started to be used) and many others seem to not know what it means, evidenced by only understanding the current law enforcement use or their admission that they had to read wikipedia.

That said, for many people, it is a hostile phrase that refers to privileges that law enforcement provide for each other and those close to them but not others. Things like letting people out of tickets, misapplying situational judgements to make a victim look like the perpetrator, lying on the stand about it, etc.

In that context, it’s a phrase with bad optics. I see presumably why they chose the phrase but that also presumes they were not aware of how it’s used by many American police officers. It would otherwise seem incredibly tone deaf; well past the 70% figure among those circles.
