Hard to say if the young one was even armed or not , I tried looking at the video to see if he may have been carrying concealed or not , hard to tell . There looks like he could of had a concealed holster on his right side , but if he wasn't armed at the time , he should have been .
I would give him the benefit of the doubt that if he wasn't armed at the time & had to pick up or grab & load a firearm . I don't think any sane person would do anything differently ( if unarmed ) in that situation.
I guess there could be some couch commando's that would say they would kill them with all with their bare hands , because they don't need no stinking gun .
