PCSO is not a voluntary position they are a civilian member of the police staff employed as a uniformed no-warranted office
You are correct V, PCSOs and TPCSOs are non-warranted officers who have effectively taken on the role previously filled by Sgt. George Dixon (if anyone remembers him) in as much as they are effectively in a public confidence and intelligence gathering position. They have little paperwork to deal with so can spend more time on the streets. They are gradually being accepted for what they are but there is still relatively little understanding in certain sections of the press as to what they actually do. One national daily (Mail?) recently wrote a piece where the journalist stated that in one force area PCSOs had only arrested one person in over two year. That would put them considerably ahead of expectations as they aren't there to arrest anybody.
What they've often done is to arrange activities that keep kids off the streets, something youth clubs used to take care of. In my area they've attended at a pensioner's flat where the back door had been kicked in and a few items of sentimental value had been stolen. After the burglary two P.C.s took the crime report and a CSE dusted for prints. After they'd all gone the PCSOs checked gardens and searched bins and managed to find most of the bits and pieces. They took them back to the lady who invited them to stay for a cup of tea and biscuits. While one put the kettle on the other looked at the door and frame and rang the housing association to have a better door fitted and also got the Police Press Officer to tell the local paper about the housing authority's good work.
While drinking the tea the old dear started to tell the two officers about some of her neighbours' strange behaviour. "Them at number 23 are a bit strange, they get deliveries at all times of the night. Teles and all sorts of things. Mind you, them at 37 are a bit odd as well. On the sunbed all night they are. You can see the light through the attic window.
So that was a Receiver and a canabis farm sorted in one visit. That is what they are really all about.
