hi Steve, I don't think it is about politics, or even the EU although granted it has an effect.
it is far more important than that, and indeed goes to the very fabric of so called modern Britain, when even a member of parliament is not safe walking the streets, what hope is there for the rest of us.
all I would say on the subject is looking back 40 years ago [something the younger generation cannot do] we had a reasonable expectation of security, and safety on the street, and within our own borders, but not today, and in another 40 years who knows.
our local MP was a local man ex JP and well respected by all whether you agreed with his politics or not, now there is no respect for anybody, least of all MP's and it's going to get worse, my father had a saying, " you can take the animals out of the Zoo, but you cannot take the Zoo out of the animals" when you close all the Zoo's where do you put all the animals, think it's called care in the community clearly it doesn't work. does it!!.
