Is his name Otto? "Don't call me stupid!"
YTF would anyone need 5 black pistols with muzzle cans? (Also, 2 of the other guns are both M-4 Carbines. There's no reason to have 2 of those, either.) Even if you're going for the Guns Akimbo Perk, you only have 2 hands, and 2 hips. The muffler makes concealment difficult enough, without 4 New York Reloads, so any covert sublty is pretty much ruined by having enough to spell out letters with handguns.
This is honestly how we can stop the spree shootings. Not anyone who [Likes] an image like that on Social media, but anyone who has no concept, whatsoever of "Enough Guns" is just the kind of Pathology we need to be profiling. By the time they decide where they want to use such an arsenal, it's too late, bodies are already dropping.
The FBI knows the profile, they literally wrote the book on them. Honestly, all they have to do is print it up, it will fit in a fucking Pamphlet they can distribute to School Councilors, Military Recruiters, Police Academies, and Security Companies.
At the very top of the list, these guys ALWAYS seek to gain power, and authority Legally. We don't even need to go on a Witch Hunt. They will gladly come into the Police Station and ask for an application, because Law Enforcement/The Military is the best place for them to Assert Power. (Unless they can get elected to Public Office, or are born the CEO of a Fortune 500 Company.)
The recruiters just have to know what to look for...
