From the Guardian:
Pensacola shooting: Saudi student kills three at Florida naval air station, says official

See, in relation, this post I wrote from 2017, in which I argued that Trump's Muslim ban didn't make any sense, because (I argued) Iranians, who haven't committed any acts of terrorism against US citizens, were included in the ban, but Saudi Arabian citizens, who have committed acts of terrorism, were not.included.

I bring this up, because I suspect somebody somewhere is going to argue that this incident is more evidence that the Muslim ban is necessary.  But actually it's evidence that Trump's Muslim ban is not working.
