"The Minuteman Project (MMP) is a citizens' Vigilance Operation monitoring immigration, business, and government. "
Is that from their own description of the organization? If so, the choice of the word "Vigilance" is probably no such a good idea.
"Vigilance Committees" were the names of the original vigilante organizations. Not a good choice of words, if it's from the MMP.
It is from their own self-description.

I guess we all have to stop using the word Vigilance?
