If a Parent did this to a child? What about a Teacher?

"TORONTO — A Toronto teacher failed to properly assess the safety risks at a swim site where a 15-year-old student drowned during a school canoe trip but his actions did not meet the threshold for a criminal conviction, an Ontario judge ruled Wednesday. "       If you had kids over in your back yard and you allowed them to swim in a deep pool.  And a Black Child who could not swim drowned,  would you be responsible? What does this case tell us about professionals in Ontario? My heart goes out to this family throughout this terrible situation.
