IF TRUE....Both the State Department consular official overseas (who granted this person’s travel to US authorization at a US Embassy or Consulate) and then the ICE official who actually stamped his entry in his passport at his port of entry—and let him into the USA, should both be made public. That is, if this person is a non-citizen who was on a visa in the United States. Failure to perform full background checks and perform the usual due diligence, may have lead to the deaths of all those students.

I doubt whether they ever do full background checks on student visa applicants (unless they come from Iran). And filtering out a very small number of people like this from 500,000 foreign students who come to US is basically like looking for a needle in a haystack.
