That's the real American tragedy, that we've been beaten into believing that "nothing can be done to prevent this." Something COULD be done, it just won't be. I'm sure as we learn more about this reprehensible idiot who caused this sick misery, we'll come to find out there were all kinds of red flags on his social media posts and his emails and his past arrest records and yet nobody bothered to take them seriously, or cared enough about him to connect him with psychotherapy and medication. Sad. Because the truth is, this kind of thing is always ENTIRELY preventable - if only Americans were smarter about gun control and less obsessed with violence as some sort of solution (which it never is). A sad country indeed.
