Why they did it is obvious. They wanted to show that guns were being sent across the border and this would have given them an excuse to control guns tighter. Planted evidence at the scene of a crime. Oldest trick in the books.
re: “Planted evidence at the scene of a crime. Oldest trick in the books.”
That’s certainly a simple, and possibly accurate, explanation.
We should also note that Obama lived and worked in the same neighborhood as the US end of the Blackstone Rangers / El Rukn / Libya terror plot. In that plot, the Libyan government arranged for a federally-funded US community group to get large amounts of weapons and money in exchange for promises to carry out terrorist attacks in the USA. The US headquarters of the Blackstone Rangers / El Rukns was at 3947 S. Drexel Avenue, Chicago, IL, 1.6 miles from Obama’s current Chicago address. It’s hard to believe that an active community organizer in that area wouldn’t have had some contact with other community leaders (legitimate or illegitimate) in that area.
(full disclosure: I lived on Drexel Avenue, just a few miles from that HQ, when I was in medical school. I was not, however, a community organizer, and, to the best of my knowledge, I had no contact whatsoever with any community leaders from that area, other than leaders from the University)
I just think that the “gunwalker” case seems to have a lot in common with the Blackstone Rangers / El Rukn / Libya terror plot. “Gunwalker” may be a lot more than simple planting of evidence.
