That's a bit surprising because UK police have a great rep internationally for dealing with informants. This smells a lot like a community policing failure, which UK police also have a solid rep for.
Not the police's fault, more society in general. Hattersley is one of those area's that operates on its own plane. If there's trouble, they'll deal with it themselves, rather than involving the authorities (something usually joked as around here as 'Salford justice' - proper eye for an eye stuff). Its pretty much controlled by local gangs rather than effective government. I know it sounds like a description of Krays era East End London, but there are pockets like that still - mainly in deprived areas and large former council estates (of which this is one). The police will do what they can, and respond to any incidents. But even when they are helping out, their presence is not welcome, and you get the feeling whoever called the cops will have a brick through the window that night.
My reaction to two women taking the call wasn't 'women can't deal with a problem', far from it, it was more concern on the location being an area where police do suffer abuse for their presence anyway, and two female officers are an easier target for cowards.
In this case it wouldn't have made a difference, nothing could be done, it just raised a bit of an eyebrow, thats all.
I've always said to my mate who lives down the road that the sign's on that estate informing people its a 30mph zone are actually a minimum guidance for public safety. (Funnily enough, he lives less than a mile away in a very nice area - next door neighbour being a former Premiership/International footballer - just shows how vastly different area's can be)
