While acab is probably too generalized a term to apply to ALL police forces in the world… Interpreting acab in absolutes is also kinda silly and needlessly pedantic.
If I were to say all Nazi are bastards… Would we be making the same arguments? Surely there were Nazi that were forced to join the party, surely there were Nazi giving years of their lives to serving their communities, risking their lives and health.
The point of ACAB is to highlight the inherent and institutional failures of policing actions native to the vast majority of western democracies. Where police are primarily utilized to protect property and institutional power, rather than protecting the most disadvantaged communities in our society.
