The recent investigation by WY police regarding comments made on twitter (non threatening and not racially motivated) has prompted me to think about my own involvement with them and the publicised screw ups they have made over the years.
Without researching, what comes to mind is:
Yorkshire Ripper.
So many missed chances. More women murdered.
Womens concerns/alerts dismissed because they were prostitues.
Hillsborough.
Failure to manage the crowd then blame planted at the fans door.
Jimmy Saville.
They knew.
So many raised concerns.
They ignored.
For 30 plus years
Rotherham.
Concerns were raised.
People were silenced.
So many girls became victims when the police should have protected them.
I am sure there are more 
My own experience was aged 19 beat up by my bf.
Got home and called the police.
4 hours later I was visited.
Female officer refused to write down my statement as I had been drinking. I had but the beating lasted 2 hours before I escaped and I was very sober by then. She also said it was a waste as I would only go back to him. He had never hit me before and I had no involvement with the police prior to this.
No photos taken of my busted lips, nose or black eye.
A week later I was contacted by a detective who wanted to interview me. They had arrested him the night before for a fight in Leeds. When they charged him my complaint showed up.
They came to my work and interviewed me for 3 hours.
He was charged with the fight and my evidence helped but he was never charged with my assault. That was forgotten. Not seen as important. He was given 3 months for fighting over football. I never heard a thing from them.
I have no trust at all in Yorkshire police and feel they need to be investigated.
AIBU?
