It's interesting to see that the first attack on a Muslim was a 'personal dispute' - but what is reported is that the attacker left his home, travelled to the home of someone he knew and attacked them when they opened the front door. I'm interested to hear more detail about why that is being treated as a 'personal dispute' and not a racist attack.
The Met police tweet pinned by the OP ignoring the attempted murder of the Muslim victim is disgraceful and racist.
I would also question if the actions of a man who very recently left a secure psychiatric unit really tell us much about prejudice in the UK. Sadly it shows that psychiatric risk assessments and management are inadequate. It'll be very interesting to see if he is deemed to have full responsibility for his actions - may be a case of reduced responsibility on mental capacity grounds. It'll all come out in court.
