What Part of "Due Process" Do Minutemen Not Understand?

There's no way for vigilantes to distinguish between illegals and Hispanics who are citizens or who have green cards. Vigilantes have neither the legal authority to detain and question suspected illegals nor to arrest anyone. In fact, any Hispanic citizens who are approached by armed vigilantes would rightly fear for their safety and would be entitled to use deadly force to protect themselves. So, you Minutemen who keep advocating illegal vigilante activity, WHAT PART OF "DUE PROCESS" DO YOU NOT UNDERSTAND?
