2014 - we had the referendum on Scottish independence. There were a few yobs out on the streets just after. (NO voters by the way) Those of us who voted YES were a bit disappointed but that was it. 10% of a difference was fairly conclusive. No horrible fights over it. It's past (till the next time!)
2016 All mayhem breaks loose because of troubles in the Tory party. Really , they deserve to burn for what they've done to this country.
