What matters more, why they became an officer, or the impact. Far too many police officers violate citizens' rights without consequence and these "good" ones never seem available to counter them. Silence in the face of prejudice and cruelty is not "good." I have family members who are police officers, but their individual good deeds on a personal level doesn't negate the fact that policing, as a system is flawed, and does not provide safety, particularly for Black and Brown communities.

ACAB is not an individual diss on officers, it's a way of raising awareness (among young people) of the systemic nature of the problem. When the blue wall protects other officers from accountability, then I'd say there are no good cops, because their purported goodness doesn't act as a protective factor for the community.

The reason why officers trying to help are shut down is because the problem is structural. You cannot individualize your way out of a structural problem. Thus, their purported goodness is irrelevant, in the context of these abuses.Typically, I don't use the term "ACAB," even though I do not believe policing can be reformed--a new system of public safety must be rebuilt from the ground up However, I can certainly understand the frustration of those who do.
