"Free Speech" slightly more expensive
This is a good trick; if you don't like what someone says at a public forum, just send the FBI his way. From a Washington Times article : "Jim Bensman thought his suggestion during a public hearing was harmless enough: Instead of building a channel so migratory fish could go around a dam on the Mississippi River, just get rid of the dam. Instead, the environmental activist found himself in hot water, drawing FBI scrutiny to see whether he had any terrorist intentions."
