@Pepe. I just posted a story on the front page dealing with Michoacanos in Santa Ana California who help support the AUD in their home towns. I referenced you and your story, specifically the question you raise about whether the US govt. will prosecute those that contribute to the AUDs.
That is a very intriguing question and I think may be a ticking time bomb.
The Mexican "war on drugs" has been carried out mostly in furtherance of the US war on drugs. Your question makes me wonder if the EPN's reform concerning terrorism that he passed in Feb. was prompted by the US. Terrorism has not been a big issue in Mexico, but we all know of the rights lost in the US justified by the "war on terrorism". That may be what is happening in Mexico.
Words are powerful weapons, be careful how you use them.
