Notice how 100% of all UK media coverage is on the riots and NOT on the background of the murderer and his family, and the immigration disaster that led to this savage crime, one of the worst in British history.
The old Brits would have had the yute dancing on a gibbet tree on Tyburn Hill by now, and his family would have been lucky to avoid joining him.
There would have been just as little coverage on the murderer had he been a white Scotsman. That's because of the strict UK rules on prejudicing a fair trial and contempt of court. This means that the media have to delay all in-depth coverage of a criminal until after trial and sentence. All they can do is publish the name (and not even that if it's a juvenile), and home location, and report anything that's said in open court. This applies whatever the crime, and whoever the criminal.
