100% irrefutable proof all mass shootings are staged

Guys I have stumbled upon something HUGE. Like most of you, I know all of these mass shootings are psyops by the government to keep us afraid, but I never felt I could prove it. So the other day I go to the store and buy an AR 15 and about 1,000 rounds. I go home to set up a few experiments. I set up a coffee can about 10 yards and take a few shots. Nothing. It doesn't even budge. I take a few steps closer and take a few more. Nothing! I walk right up to the can, point the gun directly on the can and unload the entire magazine. The gun kicks and makes a lot of noise (just like we see on tv), but the can doesn't move. At this point I'm stunned. I go in the house and point the gun at my cat. Again I pull the trigger. Lots of noise, the cat runs like hell, but he's unscathed. I'm thinking ok, it has to be the gun or the ammo. So I break into my neighbor's house a take every one of his rifles and pistols. I proceed to load every one of them and pull the trigger to no effect other than a kick with lots of noise. There is no, I repeat ZERO, evidence of any projectile. I even point the gun to my head a few times and pull the trigger. Hurt my ears like hell, but I'm fine! Then it dawns on me....ALL GUNS ARE NOTHING BUT GLORIFIED CAP GUNS. There is no such thing as a gun that fires a projectile. I immediately called my brother, who is a physicist. He ran a few quick calculations and was stunned. He said that for any bullet to do the amount of damage depicted in movies and news stories, they would have to fire with such force that the average human would not be able to hold the gun. That or it would certainly EXPLODE. So there you have it, folks. 100% undeniable proof all mass shootings are fake. I promise to run more experiments and continue to report my evidence. SPREAD THE WORD!!!!!
