So, to clarify...
A female who it seems was suffering from mental illness camped on a roundabout.
The authorities weighed up the social, legal and medical oppositions. Consulted with relevant Law and Health bodies and when sure of the correct measures, acted. I could be wrong, but I think this is what they get paid to do, what they are trained for and what they are legally obliged to do.
What didn't happen was the authorities acted to appease a vocal few whose slogans are '...this ain't what I pay my taxes for' and the '...my Dad didn't fight the second world war just so _____ can do ______ (please fill in blanks)'
Luckily for society it is exactly what we pay taxes for and exactly why 'my' father fought in the war.
.........(well, to be fair he was already in the RAF in 1939 so he didn't have much choice).
