Are you open to critisism Z?
1st of all, I've never found a reliable source to Yamamoto's quote about 'every blade'. While it's a noble idea, You'll need to site a reputable source.
Don't call 'em guns. They're 'firearms'. 'Guns' sounds redneck (not that that's a bad thing). You're not getting any points for that. Handgun is ok, as is shotgun. If you're referring to firearms in 'general', use firearm as the descriptive term.
I won't critique your entire paper, but please check your punctuation.
Read, read, read... and correct.
It makes a HUGE difference in your presentation.
