The resemblance is uncanny. The least conspiratorial explanation is that a certain look tends to find themselves ridiculed and isolated in similar manners in cultures that share many of the same values. I don't know if I can fathom the chances that these two people chose the same extremist act without external influences.  That's some "Catcher in the Rye" shit right there. It could be that these two kids fit a profile and were targeted for manipulation. Or it just could be they were tired of the shit in their lives. Who the fuck knows?  One thing is interesting reading articles about both of these shootings. MSM is going out of its way to stress the use of assault rifles by the perpetrators and the police responding with handguns. Give it another 10 years, police are going to be patrolling with tanks, searching homes door to door under some bullshit "public safety" excuse that magically negates 4th amendment protections. Given how much alike these two look like each other, I tend to believe they fit a "profile", were targeted for manipulation. I can imagine that it's technically possible for the manipulation to be multi-faceted over the internet appearing to be both "internet friends" and anonymous internet adversaries with increased rates of imagery and information reaching these individuals over multiple social media websites/ad networks/news feeds, etc to twist their minds over the months leading them to act out with the same extremist acts. Mk-Ultra literally can be piped into a single person's perception of the world via the internet. Do you believe the ability to  target & customize ads is all that they're using that technology for? You're living in a dream if you do. They can customize the world view they want you to have depending how connected you are. Why is it that the more connected people became the more divisive they became? M.A.N.I.P.U.L.A.T.I.O.N. The internet really can be used to warp and twist one's "reality". "Reality" is the only word in the dictionary that should always be used within quotes.
