As I said, i do not support defunding despite supporting ACAB.. so we agree there.
But since this logic assumes a cop is bad for not arresting their partner or other cops when those other cops are bad, it is an arguement that all cops are bad, presuming you agree a cop that doesnt act is a bad cop...
And when we say all we are talking 99.99% of cops.. the only exceptions would be a cop that has arrested other cops when on duty... which is virtually non existant.
