In my humble opinion that article is just left wing dribble. It has no crediablity. Atzlan the southwest part of the US some Mexicans feel that the US stole from Mexico after the 1849 Mexican War.. They fail to realize that the US defeated Mexico in 1849.
It is true that NOPD did shoot and kill 5 men as said in your link. But the conspicary thoery?..I just don't believe it. Why would the US Government do such a thing? Then congress immediatly passes a bill to spend $51.8 billion dollars to rebuild and supply the area affected. That's $51,800,000,000 green American dollars. Free Asia 200 do you really believe that entire story??
