Over the last week spokesmen for the border patrol volunteers, who dub themselves Minutemen, have said they will not attempt to detain Mexican illegals, but rather report them to the Border Patrol and track them till they're apprehended.

Despite the assurances, Mexican officials met with the mayor of Douglas, Ariz., on Tuesday to discuss how they will handle potential violence, KVOA said.

Last week President Fox warned at a Mexico City press conference:

"We totally reject the idea of these migrant-hunting groups. We will use the law, international law and even U.S. law to make sure these types of groups, which are a minority, will not have any opportunity to progress."
