I love how you have so little self-respect that you have to make up BS like he's an illegal immigrant.
Not only that...
Depape had been in the U.S. for well over a decade before the attack. If he really was an illegal immigrant who was known to pose a threat to the U.S. population, then why wasn't he deported, by say, the guy who was president from 2017-2021? You know, the guy who made it a focus of his administration to protect people from supposedly dangerous immigrants? Who was that guy again?
Oh yeah he was a republican.
Well, perhaps if Trump had managed to finish building his border wall then DePape wouldn't have been a problem. No, wait, he didn't cross the U.S. mexico border, did he.
