A secret 400-page Defense Department document obtained by NBC News lists the Lake Worth meeting as a “threat” and one of more than 1,500 “suspicious incidents” across the country over a recent 10-month period.

This is incredible,” adds group member Rich Hersh. “It's an example of paranoia by our government,” he says. “We're not doing anything illegal.”
