My feeling is that it was a justifiable shooting (meaning that the shooter wouldn't be convicted if it went to trial if there was even one non-poosay-hat-wearer on the jury) and that the driver was a leftarded NPC with a death-wish who got the sort of 'heroic' end she may have fantasized about in the abstract.

That's verging on mind-reading, which is poor form, but I'll indulge in a bit more borderline ESP here.

What seems more likely to you: (A.) the shooter who was reportedly dragged along with a moving vehicle in a prior incident totally submerged his memories of that event and was just a super-duper by-the-book guy who was, alas, a bubbling cauldron of unprocessed trauma or (B.) the shooter had mulled that experience over and decided that he would never get caught out like that ever again and had been practicing his quick-draw and marksmanship and mentally war-gamed/rehearsed what he'd do in any sort of future vehicle-related scenario and that was what he did that day?

For me, the latter seems much more likely.

The whole thing was a clusterf*ck IMO.

If Eisenhower could do Operation Wetback with punchcard-era computing (if any) and without Modern-Warfare-LARPers acting like paramilitary brigades, surely (given that the gubment is tracking/listening-in-on all mobile devices, intercepts and reads all electronic communications and phone calls, etc.) it would be possible to snatch up illegals in larger numbers than is happening now without the melodrama. The fact that the melodrama is unnecessary but is happening anyway gives me a queasy feeling.
