It's always good to look at the reasons why these sorts of things happen, but that doesn't mean we should be pandering to people like this. Plenty of people are angry about the state of the country yet manage to not attempt to burn a hotel of people alive. Look at the profile of these people over the next few days as they go through court. Look at how many of them how a list of prior convictions as long as your arm. Lots of them are not disillusioned people with genuine concerns at the end of their tether with the state of the country, they're racist thugs who thought it was a good excuse to beat up a few minorities.
The people genuinely hurting from 14 years of the Tories were the ones protesting before they got kicked out of office. They're the ones that were protesting the cost of living when fuel bills were threatening to almost double in a year, and they were from all sections of the political spectrum. Those are the people we should be listening to.
