What does a bad guy or a jam have to do with throwing your primary arm to the ground in order to transition to a pistol? The pistol is the logical weapon when the primary has a failure but reducing yourself to a defence arm intentionally boggles my mind.
The proper application of a tactical sling would have allowed the transition WITHOUT the loss of the rifle. Bad tactics, bad lesson taught to novice shooters. Potentially fatal decision in a combat environment.
Slings are not just for the lazy, they are a life and death piece of kit.
