It would be tragic if the killing had a big impact on the vote.Going by the wall to wall hysterical coverage of what happened it has the possibility to have a significant impact if voters don't realise that this guy had mental issues.No-one can be held accountable for what happened other than the nutter.The next polls will tell us if it has had an impact.
It's one thing for the vote to be won by Remain based on Project Fear or whatever else they come out with but it is a serious blow for democracy if what happened swings the vote.
I think the point that (many) people are trying to make is that the poisonous atmosphere whipped up by (some) on the Leave side has created an irrational fear of immigrants, and this has the capacity to incite violence. It's clearly NOT what the vast majority of perfectly reasonable Brexiteers want to do. But you have to question the motivation of the likes of Farage (his stunt on Thursday with the "Breaking Point" poster was pretty blatantly racist). There's also been a lot of fear-mongering amongst the Vote Leave camp - immigrants will rape our women, immigrants are criminals, etc, etc. I really, really hope that the Vote Leave campaign now distance themselves from Farage and his ilk, and stops banging on so negatively about immigration.
