Seriously…dev thinks crazy Ashley can just go randomly buy a handgun…even with her having “state declared mental issues’…because it’s a gun show. I’m assuming this nut lives in Chicago…and blames all the violence on the Southside…on Indiana…hope you like your Biden gas prices you silly fuck.

Ah yes, the person who tries to bring politics into everything. Go outside bro.

To be fair the dev brought the politics but yeah, You’re right, this dudes a twat.. the whole “gunshow loophole” thing is 99% a crock of shit but im not soo neandertholic that I can’t tell when someone is using politics in a semi playful way to add something to a character.

Anonymous Fapper

Ofc, because noone with mental problems ever got/gets their hands on a gun in the USA…. oh wait…

Dude you literally CAN Do that…think it was Buzzfeed, sent in a hidden camera and showed that you can buy guns at those shows like quite literally 9 times out of 10 that they tried…just sayin.

Anonymous Fapper

Can they prove they were real dealers and not actors Buzzfeed put in? Because few years ago Buzzfeed got caught staging a story (I forget on what)..

Average characters, typical storyline, no animations. Nothing special at all.
