First attempt at watching I closed the video instantly due to extremely poor trigger discipline, not even 2 seconds in and you have your finger on the trigger of a weapon that you stated you would always treat as if loaded.
Second attempt at watching closed 10 seconds in when you put your finger directly on the trigger again. That is my last attempt. To be dead honest I would fear for my life if I ever met you in person knowing that you could potentially be carrying, from what you'd iterated you'd do in a situation when confronted combined with your extremely poor trigger discipline I'd honestly rather be held at gunpoint by a real robber.
Trigger discipline is a two way system: You either have it or you don't, there is no 'lousy trigger discipline' and from what I'd just seen within the first 10 seconds of you handling a gun I'd say you don't have it, adding the fact that you showcase such skittish behavior as to how you'd deal with a scenario where somebody MIGHT confront you I can only imagine that you'd probably end up killing somebody. Please, for the fucking good of your own safety and the safety of every innocent on the campus, give the gun back to your father, get some god damned training. I've seen little kids reviewing airsoft guns handle guns more responsibly then that.
EDIT: Oh jesus christ 2 minutes in you start jamming your entire finger into the trigger guard and do THAT? At least do a full clearance drill, while showing the camera for confirmation so you can at least LOOK like you know what you're doing. Come on man.
I'd be beyond scared for my life, I'd fucking call the cops on you, I'm sorry but I have NEVER, EVER seen such a irresponsible handling of a firearm, combined with your attitude towards dealing with anybody who might be 'suspicious' enough for you to draw on them... I would seriously just call the police right there and then.
I'm in Canada and I'll never handle a firearm within my lifetime, but at least I follow simple concepts such as your finger should not be on the trigger of ANYTHING when you do not intend to perform the action that would be execute as a result of pulling the trigger. When I use a drill I put my finger against the frame of the body even though in reality the chances of anything happening are extremely slim and even if I accidentally pull the trigger it probably would cause no harm considering the drill would just simply rotate in the air, but I do it anyways because I know that getting 'lazy' with something like that isn't an option. I do not intend to turn the drill so I ensure I can't accidentally turn the drill, even though no harm would be brought on by the drill turning by accident, it's still better to always be in control.
If I ever had a gun would I use it? The fuck NO, a gun for self defense is used as a absolute last resort, in a life or death situation where you have absolutely no other choice, however you for some reason do not follow this logic and instead seem to follow "If he's suspicious looking draw on him", functioning entirely off of paranoia fueled by stories surrounding you about people getting hurt, clouding your judgement and probably going to make you kill somebody you shouldn't.
