Sadly this is at a guess just the start of things. Personal opinions asides it was only a matter of time before it kicked off. Like it of lump it its long been bubbling and in some form or another can be traced back as far as the riots in 2011. To a degree I'm not even sure these are direct retaliations but rioting, brexit voting, retaliation attacks towards foreigners after attacks going back as far as lee rigby. Frankly i'm shocked its taken this long.
To be clear I dont condone these actions at all I can just understand to a degree why they are happening and tbh I think its just the start. Underlying problem however is the government. Like it or not the british male is getting fed up of seeing british men women and children being blown up, stabbed or runover without anything other than a concert or announcement from the government saying tut tut come on stop being naughty, and when someone is caught for terrorist acts we treat them with kids gloves give them a new identity and pop them in a safe warm solitary environment for them to think about what theyve done. Like it or lump it people like to see reactions and responses they want these terrorists to hang literally and figuratively and one way or another more of these things will happen if we dont start getting hard on those that are responsible.
