This might start a flame war, but all firearms are capable of jamming at some point, and if you shoot them enough they surely will. The young scumbag was using a bolt action 30.06 rifle without an optic, which is the epitome of simplicity when we're talking about guns, and it still jammed. I've jammed just about every bolt action, as well as pretty much any other type of gun that I've ever owned, and that is because if you shoot them a lot they will eventually malfunction. Man made things always do. Learning to overcome jams may just save your life, and can only be accomplished with practice.
