Police, cameras, inaction!
Unfortunately all this seems to be driven by government overreaction and then the passing of blanket laws which are so vague the interpretation can be used for all sorts of circumstances in the name of anti terrorism. Then the government give the police targets i.e. we will remove your funding and or job if you don't do as I say and as a result the police and PCSO's have to go about stopping people on the slightest whiff of suspicion to satisfy the beancounters unfortunately this errodes public confidence and leads to people instead of helping the police when it would be appropriate to just antagonizing things. So in summary I blame the government who 'knows whats best for us' for causing the silly situation.
