Bill anyone who fires a gun is capable of missing the target, and unless they can guarantee that there is no one in the area which can possibly be hit ,then it is not a safe shot and can be considered irresponsible imho.The fact that people do shoot at elevated targets,particularly on roofs ,where you cannot see behind the target,unless there are no walls,runs the risk should they miss of accidentally shooting someone or something,and this is even more dangerous with an fac air rifle.The only safe shot is one that should you miss , or the pellet ,bullet et should pass straight through the targ
