Well then I fully expect to see the police and the courts here crack down swiftly and decisively, making mass arrests and fast tracking those guilty of rioting through the courts and straight to prison for the maximum sentences possible. Ditto those found guilty of any form of racial abuse or supposed incitement to violence on social media. That should nip the whole thing in the bud.
They can release low level and low risk criminals a bit early in order to make space if required. If it was appropriate and necessary for the post-Southport rioters of last summer then it will be appropriate and necessary for this. After all, there is racism, sectarianism, religious difference and culture clashes at the heart of this issue just as there was with that.
Let's see if that happens.
Also anyone convicted who isn't already in receipt of a British passport should be returned to their country of origin once their sentence is served. It would almost certainly happen in most other countries in Asia, including India and Pakistan so it should happen here.
