How are they using large body grip traps?. Doesn't your equipment need to be approved species by species?
The law says that you must use a tool designed to catch the animal with a snare by the foot.It also says that steel jawed traps and neck snares (spring season only) are illegal. Neck snares are permitted in the fall.
A larger body grip is set so that lies flat on the ground. A snare is loosely tied to the upper jaw. When the animal sets off the trap, the snare closes on the foot as the trap is shaken off by the bear.
The SzS bear got shot at, and missed, by a cottager. It might be a few days before it comes back - or it might not come back.
