The weapons in the report are guns that were sold to the Mexican Government years ago. At least the M203’s, M16’s, and Barretts. The rest were probably purchased by the Mexican Government from other nations.
Isn’t really a major jump to figure out how these guns got into the hands of criminals. This is just another reason we need to get rid of the stupid gun control laws here. We will be facing guns like these at some point when these gang bangers push the envelope. As the cops like to proclaim... we need to level the playing field.
