FlaxMeadow, I would call the targeting and then the abject failures of the authorities in the Rochdale cases a combination of the class system and ingrained misogyny. The wielding of male power across ethnic groups resulted in the silencing of female victims of egregious crimes and the women who believed them.
The girls who were victimised by the criminal gangs and by all the institutions supposed to protect them were up against a power structure trained both formally and informally through cultural exposure, regardless of racial makeup, to attach no value to the word of lower class young women and especially those suspected of being sexually active, of drinking or drug use, or who were seen as 'damaged goods', and to value the word of people with educated accents, job titles, and confidence when dealing with the authorities. The whistleblowers were women and they were also ignored.
The institutions which dismissed the girls in Rochdale were conditioned to see a certain type of girl as unreliable. The gangs specifically targeted girls who were from dysfunctional homes, or in the care system, who were very vulnerable, the least powerful and least protected members of the society in which they operated. They did not hang around the playing fields of private schools looking for their victims.
In the US, black people are targeted by police regardless of socio economic status. In fact, a black male teenager who lives in an affluent neighbourhood stands a high chance of very poor treatment by police for just walking on the path outside his own home. Policing in black areas tends to be heavy handed, and the proportion of unsolved crimes in these areas tends to be high. The conclusion many black people draw is that police are focused on protecting white people and white neighbourhoods and not interested in serving or protecting when it comes to black crime victims and black property loss.
Amy Cooper in Central Park thought she could get an educated, middle class, well spoken black man to regret his boldness in asking her to restrain her dog if she invoked her whiteness and called on what she assumed to be the defenders of white interests to teach him a lesson, perhaps the ultimate lesson.
There have been multiple examples of black men and women murdered in their own homes and gardens by police who were called by white neighbours, and then there is the drip, drip effect when thousands of black people experience being held up on the street by police and asked to account for themselves while they are going about their business, because they 'fit a description' which could be as vague as 'black man aged 18-30', 'wearing jeans', 'wearing a baseball hat'. As long as you are black you are fair game. Ms Cooper knew that.
The dynamic in which one group is valued and one group is automatically, reflexively discredited works the same in both racism and misogyny with the complication of classism.
