The reasons for "two-tier"/anti-White policing by White cops

[Redbeard7]

1. Every cop, especially every White cop, is terrified of being another Derek Chauvin (tried by the media, imprisoned and stabbed more times than Julius Caesar, despite evidence to pardon him) so they do not surveil or punish "minorities" effectively, whereas they can tyrannise Whites and not be accused of "racism" (and cops are trained to regard the public as the enemy, with the state as their master).
2. The repressed aggression that White cops feel towards non-Whites (who are far more hostile towards them on average) is redirected towards Whites as a politically correct target as well as being an extension of their own ethnomasochism (this also goes with the grain of their frequent bullying tendencies: cops are consistently among the worst offending occupations for domestic violence, if not the worst)
3. Cops are indoctrinated with implicitly genocidal anti-White "critical race theory", pro-black "systemic racism" narratives, Noel "destroy the White race" Ignatiev's "white skin privilege" etc. and that's after decades of anti-White/"leftist" school and media indoctrination as children/teenagers, neutering them in the face of non-White aggression and increasing hostility towards Whites.
4. Cops fear disproportionately criminal non-White groups (especially Muslims, Africans and Roma) but do not generally fear Whites (who have "too much to lose" economically, little to no institutional identity protection, an undue respect for the cops and, being atomised and emasculated, feel they need the cops for "protection" against the aforementioned ethnic aliens), increasing passivity towards non-Whites and aggression towards Whites.
5. In order to lessen complaints of "racial profiling" and to "counter far-right narratives", cops reduce their policing of non-Whites and increase their policing of Whites, facilitating non-White violence while artificially inflating the crime statistics, demonisation and gaslighting of Whites ("social justice" in action).
6. Bertrand de Jouvenel's theory of "high and low vs the middle" argues that it's a perennial elite strategy to empower and expand the underclass to attack and even ultimately destroy the middle. The underclass can never form a new elite but the middle can and the underclass is only a serious threat to the elite if it's allied with the middle. Cops are bribed, empowered (to an extent) and used as pawns by the elite, primarily to suppress the middle despite usually being from the middle/White themselves (at least currently, given their increasingly pronounced tendency to hire hostile, corrupt and incompetent "diversity").

Taken together these points are extremely effective in explaining why the police, including White cops, are so intensely anti-White.
