Hey You Kids Out of that Jello Tree

Paquette v. School District No. 36 (Surrey), 2014 BCSC 205 deals with a child climbing onto and falling off of a school building roof. So every adult knows that kids will climb up roofs an every child knows that they shouldn’t do it. Should the school really be 75% liable? I wonder what happened to the staff member that was herding these kids off of the roof?
