A tragic event. I hope the perpetrator is prosecuted to the fullest extent of the law. Now, why don’t you go dig up some story of a documented American killing several people, or do you only care about the victims when the perp is undocumented?
The most important reality is this: ILLEGAL ALIENS AREN’T SUPPOSED TO BE HERE. Therefore, any deaths they cause would have been prevented by keeping them out. Any deaths they cause are by definition ABOVE AND BEYOND any deaths that otherwise would occur.
Suppose I’m the principal of a high school. The law in my town forbids anyone from entering school property unless they are a student, staff member, or on authorized business. But as principal, I ignore that law and start allowing people off the street to hang out in the hallways, to eat for free in the cafeteria, to get free treatment from the school nurse, and other such nonsense. I justify it by arguing that they’re “needy” and that, on occasion, they help out a little around the school with repair work (they work cheaper than if I brought in an legitimate contractor).
One day, one of these unauthorized people, hanging out in the hallways illegally, kills your child. Are you saying that I, as principal, who knowingly allowed this person into the school in violation of the law, would have no responsibility for this crime? Would you say, “Golly, gee whiz, my child is dead, but really it could’ve happened anyway. There are cases where kids are killed at school by other kids. I have no reason to be upset with Principal Puroresu for allowing vagrants to hang out in the halls. I mean, after all, they needed meals and health care and some of them painted the bleachers for below minimum wage."
If you would say such a thing, you’d be a damn fool.
