Exactly: more gun laws will not solve a cultural problem. Blacks are shooting each other and others not because of the existence of guns, but because they are caught up in a culture of gangsterism. In the UK, where guns are harder to get, they instead attack each other with knives and machetes, often in epic street battles in London. 

Most black youth go to school 'tooled up' and are quick to use knives in any dispute. This is the source of the violence and bloodshed.
