The number of incidents is very small in the grand scheme of things, important to the individuals, note worthy, but relatively small. I think the police reported something like a 50% increase in reported incidents for a comparable time scale. But that 50% increase meant a rise to 80 reports.
But I don't think it can be disputed that in a small number of mentally deficient people, the 'victory' of the anti immigration campaign has emboldened them. Hopefully for a very short window of time.
Not a twitter anecdote, not a reheated myth, there is an Italian cafe in the centre of my town that has been there all my adult life. On the weekend they had one or two people going in there and telling them to 'go home'. It's pathetic, it's one or two people in a town of thousands. They've since said they've been absolutely swamped with well wishers.
There are pricks out there and they've been encouraged to be even bigger pricks by Farage.
