Conspiracy is a criminal offense; and under the federal statute, it does not require proof of an overt act in furtherance of the conspiracy. See United States v. Shabani, 513 U.S. 10 (1994). Know this: The surest and swiftest way to lose your right to have a gun - not to mention the right to life, liberty and the pursuit of happiness - is to point it at your government. Those who run afoul of the law, will suffer its sanctions.
