Yes, the Yorkshire police forces in general, West or South, have historically been inept at best and deeply deeply fucking corrupt at worst. West Yorks fucked up for years with the Ripper case, following hoaxed lines of enquiry that led them away from Sutcliffe, who was always in their sights, and persisting in misogynistic beliefs that lead them in the wrong direction (that this was about killing prostitutes when multiple victims had zero connection to the sex trade) and South Yorks fucked it up with Watkins, good style, treating the women who complained like stupid annoying lying bitches because the accused was a white male celebrity pop star wanker. Throw in Jimmy Saville too - Scarborough ie. West Yorks was his hometown - he had massive, gangsteresque connections with W. Yorks police going back to the late fifties.
The Rotherham case (and really this is a countrywide phenomenon reaching far beyond Rothers - anywhere with a significant Pakistani or occasionally Somali 'community' basically) is also a fine example of their corruption and ineptitude but it goes deeper than the police force alone - it goes all the way to the Home Office, eventually. At one point in Gordon Brown's reign, 2008 I think, his home secretary, the ghastly bitch Jackie Smith (she who put porn films on her expenses for thre taxpayer to cover) issued an offocial writ to the police not to persue Muslim grooming gangs, the wording being that those 'exploited have made an informed choice about their behavior and it is not for police to pursue."
This infomation came from Nazir Afzal - the chief prosecutor who conducted the public enquiry into all this shit a while ago - on a radio show in 2018 or so, and was promptly pushed under the rug by the BBC etc. Scrubbed, basically. You can find the odd transcript around but very little reporting at all, because the implications a- the police and politicians were enabling rape on an industrial scale so as not to upset core Labour voters, as well as the fact that nobody wanted to deal with the likes of the Bradford riots again on their own watch - are huge.
