That's not true, cops are the physical enforcers of the laws written by politicians sold to the capital system and, as such, they tend to profit from the value stolen from the working class in benefit and salaries which are always paid during difficult times. You could see that during the pandemic, when doctors and nurses had their pays suspended but police forces did not missed a single month of pay. Furthermore defense spending is (for most of contemporary states) one of the few budget voices always rising and never shrinking. Cops are scum and I don't intend to see scum as a fellow worker. If you disagree with me answer this question: would you prefer to sit at a table with a firefighter or a cop? If the answer is a firefighter ask yourself why and then come back to this post

Absolutely. We don't need to do mental gymnastics to make reality fit with Marxian nonsense. It's completely possible to have different factions of workers with different interests in the real world. Cops are just one example, but there are others, albeit the conflicts tend to be more narrow.
