The recent shooting of an unarmed black teenager in Florida by a neighbourhood watch volunteer has plunged the U.S. into a divisive debate about race relations. It is not the first racially charged incident to have occurred during Barack Obama's presidency.

Health officials say 70 people were hospitalized after a chlorine incident at a public swimming pool in the B.C. Interior.

This was serial murder, racial murder, and it stunned the country and its leaders who just happened to be in the midst of an already bitter and racially divisive presidential election campaign, Don Murray writes.
