Monday morning went for a walk through Regent Park, the fifty year old public housing development. This on the Monday after four people were killed by gun violence, one of them an eleven year old boy caught in the middle of a gunfight at Jane and Sheppard. Michael Bryant says - once again - it's time for another government to get tough on guns and gun crime. Of course he's right, but my walk this morning brought home the second half of the mantra, "tough on crime, tough on the causes of crime". Housing has become the great orphan of social and economic policy in Canada.
