We could say the same thing about the armed forces or teachers. I would agree if we were to call them factions within a larger entity, they certainly are distinct enough from one another, there is some degree of infighting, but I feel that in general a member of the governmental caste feels greater affinity for other caste members than they do the public at large, and that is why it makes sense to look at them as a single unit. At the end of the day, individual police officers aren't elected, the only form of redress we really have in our system is the remove the leadership that allows these things to happen, we haven't done that and nothing has changed, that shouldn't be surprising.
