i see what you are saying but all i was doing was stating what i remembered what was said on radio at that time 
and this isnt a dig/jibe etc and all criticism is welcome after all we all come here to put our views across 
There was a belief that the reason the police closed off so much of London for this mans protest of the bridge was not just to avoid a possible messy scene, but also to highlight his plight.
Lets face it, if the police had not closed so much off, I don’t think the problem would have got so much media attention, remember there will be a lot of police officers in the same situation.
i totally agree with this and would not want to wish that on anyone
