He's right about Ice being the American Gestapo (An immoral group that thrives on bigotry and hatred)
But claiming MOST cops are good when not even half of them are. (Even his most tantamount predecessor Alfred Hitchcock feared the police, and for good reason too.)
When we say ACAB, it's not a commentary on the character of individual pigs, but rather an acknowledgement that individual character is irrelevant in a corrupt system.
How many honest cops does it take to change a light bulb? Honest cops have never changed anything.
That being said, ICE obviously has hired from a pool of people who are too violent, incompetent, or stupid to become your regular neighborhood pig. They really are something much worse.
