As the murder investigation into the appalling and tragic death of PC Andrew Harper is on going https://www.bbc.co.uk/news/uk-england-berkshire-49726196 I am sure I am sharing thoughts others have already stated long before me; not preaching, just asking:
What exactly do people want from the Police?
We pay for these men and women to work on the "front line" for us dealing with enquiries, handling difficult and serious situations. There is no small section of society or victim group deserving only of the police attention to deal with their concerns and everyone else can go to hell. The police represent all of us (good, bad and indifferent) and we represent all of the "front line". And if you are not supporting the safety of the police on the streets then what happens if officers do not want to do the job anymore, what then?
It is worth taking 5-mins to look at the list here:
