To do this all the government has to do is label you a terrorists. Our homeland security under Janet Napolitano has already labeled soldiers, conservative organizations (that means us at Free Republic) constitutional strict constructionists and other patriotic organizations as potential terrorists. I do not trust any president of any party with this kind of power.
ps
Muslims were not on her terrorist list, and this Administration has not labeled Physician Major Nissan (The killer at Fort Hood) a terrorist. They have called this work place violence.
Once guns are banned, anyone who refuses to turn them in will be automatically labeled.
