Can anyone tell me why this is a bad idea?

I'm referring to the Minutemen, who are stepping up their patrols of the US-Mexico border. To me, this sounds like a great idea. I'm in favor of significantly relaxing immigration policy, but I'm also in favor of rigorously enforcing immigration law. We can't regulate and protect the use of immigrant labor if the laborors in question have no legal status. Immigration has been one of the things that has gotten the US to where it is, but illegal immigration isn't helping anyone.
