Nazis Groups

I was introduced to a person who was a member of a Nazi group in California. He said he was leaving on a train to get some weapons; such as AK 47's. He said he intended to kill the government and take over the country. I told him I worked for h government; in the military. He said we were enemies. I just told him at the least I would survive it; he would not. I never heard of; or aw, the operatives again.
