The violence in London, England is not a case. Since 20 14, the incidence of violence in Britain has increased year by year. 20 19 so far, 1 19 people have died of violence.

However, four people died within 28 hours at the end of June, which once again attracted the attention of Londoners. Most of these violent incidents occurred in crowded places and university campuses, and most of the weapons were knives.

This fact reminds the British government once again that the occurrence of violence may be related to the decline of people's happiness, and another part of the reason may be the quarrel caused by racial discrimination.

Therefore, the British people hope that the British government can strengthen the management of knives and avoid racial discrimination.
