It’s always good to look for warning signs, for example the guy who just shot up a school posted a picture that said “born to kill”. Plus he had some Nazi stuff.
"Born to kill" isn't a warning sign. And "Nazi stuff" isn't a great indicator of random violence, though I'm suspicious of whether it rally was Nazi stuff, as some of the outlets reporting that are the same kind that would call anyone a Nazi.
This situation was as close to no red flags as it can possibly get.
