Reading the Altoona Mirror article, "Roommate: Bomb suspect a crazy kid," I noticed that this article can be taken in a new direction.
It's a travesty that these issues happen today, but is it possible that Vladislav is just a normal person with unique interests?
"Crazy" may have been a bit harsh when it comes to labeling his sanity, but seeing how "he was going to blow things up," risking the safety of others and contradicted his statements doesn't seem to be out of the question.
Being crazy is to be mentally deranged in an aggressive way, and after digging into the claim, not only was Miftakhov rational, he also had a concern for safety.
Having experience with his hobby, he purchased anti-static spray, which can be used to prevent static from igniting bombs in storage.
To address why he may have contradicted his statements to people, it may have been his way of protecting what he loves, his hobby.
People make mistakes, have interests, and would protect what they love. If Miftakhov's interests were directed toward the right program, Miftakhov's findings might make a positive impact.
