I think I know what you want to imply, but did you note the complete absence of race or colour in OPs comment? And alos the completely different circumstances, crowd control vs. standard law enforcement?
I did notice the absence of race or color and you will note my comment does not include any notion of race. You added race. I did note judging by appearance. You added age, out of nowhere.
Using appearance to treat people differently is profiling, though not always racial profiling. Should non-racial profiling be okay? To your inclusion of age, should we treat gatherings of youth differently than gatherings of the elderly?
The GP says "...for the police to target...". No distinction is made between crowd control and standard law enforcement.
