So, the way it works is that the PCSO raises a job - she basically phones in and speaks to civilian call-taker who takes the details. PCSO may also report this on line as member of the public can do now.
Civilian call taker takes the details as given by the member of the public/PCSO.
'Its a sticker in the widow which is not offensive and just expresses an opinion"
or
'Its a nasty vicious sticker which is committing offences'
People often embellish things to get a response and what we get sent to is often a mile away from what is reported.
Either way, the call taker hasn't seen it and can't make a judgement. If it comes in as the first version, it might just get dismissed at source
If it comes in as the second version - call taker then passes this onto a civilian dispatcher as it appears to be committing offences. Call taker might ask the caller for further details, but is just getting their view point and further embellishments.
Dispatcher then grades the job based on threat harm & risk. Dispatcher may also do some back ground checks. It may reveal that this is not the first report of such activity involving this address. They may have also been complaints from other people concerning threats, harassment & other crimes. So dispatcher might see the sticker in the window as a further continuation - either way, they believe that it merits officers to attend to obtain more details. May be nothing, may be something - but dispatcher is not willing to write it off at this stage.
So it gets graded under threat, harm & risk as fairly low down. gets placed on the the non emergency event queue to be tasked as and when.
Officers eventually go and speak to all parties.
No where does it show that the officers have spoken to the people in a menacing and frightening way. Conclusion, no offences. job closed quickly as officers want to get back to more important stuff - like their ongoing crime queue or emergencies coming in.
Why the PCSO went back around after officers finalised the job - unknown. In my opinion they shouldn't have. Unless they can give a justifiable reason for doing so.
