Since the admin was using a phys gun and dragged him to a roof, this means that an admin sit is occurring. Therefore whatever action Emmit does in this admin sit, is entirely his fault. He easily had the opportunity to not throw the grenade. The admin was trying to stop Emmit from continuing the mass rdm, however, Emmit clearly didn't listen to the admin, and he continued to mass rdm.

In the video you clearly see Emmit look at the little house, lets just assume that the admins' phys gun was the reason he was aiming there, Emmit still left clicked, during an admin sit.
