Any riot is dreadful if you are caught up in it, that goes without saying. Unfortunately they are a fact of life, all over the world, and for a multitude of reasons. We’ve had plenty in the UK, both this century and previously.
What’s really different this time is the external interference through social media, and that is something the government must put resources into. If I were them I’d be thinking about counter measures, and as well as identifying and dealing very swiftly with content, using influencers to spread alternative messages and emphasise the scale of punishments - I think we have to counter like with like.
