I posted the translation -- well most of it -- it's pretty bad...
Thanks. I fought my way through most of it before I gave up. It seemed to me to be the Mexican government complaining to the US government about the Minute Men and accusing them of abusing Mexican nationals. The US was just responding that they would assure that Mexican nationals would not be mistreated.
That is what I got out of it but if I am wrong I would like to know.
