Why are you looking for answers here for the MM?
If you are looking for dirt, go to the ACLU, No More Deaths, or Tucson Weekly leftist sites.
FR is not the Minutemen, that's why there no "donate to a fence" link here.
According to the MM documentation they want a couple of miles of substantial fence. It cost Israel billions to do theirs.
Concrete and Steel is expensive today; you expect them to make their own?
You are barking at the moon. If you have charges against the MM, ask them, not posters on this forum.
I have emailed the organization, and forwarded the email to the AZ Attorney General.
