Should rugby players be held legally liable for injuries caused to other players?

A high school rugby player in Canada has been found guilty of manslaughter over a spear tackle.

The teen was playing in a game in 2007 when, the prosecution said, he lifted rival player Manny Castillo into the air, his feet facing upwards, and drove him head first into the ground.

Castillo died from a serious head injury a few days after the incident, the Toronto Star reported.
