Violent mob attack shop where Knife wielding criminal had previously attacked before being shot

This one made little sense. The mob visited the shop where the suspect had previously violently assaulted shop staff and citizens, to protest his killing> they can be heard chanting "no peace" "racist pr*cks" " I hope you die" .."you f*cking white b*stards". Extreme irony here as they seem to be protesting on the basis that there was some racial motivation for the killing of a dangerous knife wielding criminal. The people saying "white bast*rds" outside the store are clearly racist by their words.
