Invoke federal powers and declare the NRA a domestic terrorist organization. Arrest and imprison all of it's board members and charge them with criminal acts against the common good and all American citizens. Shut it down permanently.
Hold a public trial on their crimes. Insure the NSA and FBI monitor it's current and former members for acts of sedition and treason and imprison them as necessary.
Americans have the right to pursue their dreams and aspirations without fear of murder and mayhem invoked by the NRA and it's members. This right supersedes the activities of the NRA to instill fear and mayhem into citizens at large in a false interpretation of the second amendment.
Destroy this evil murderous organization and restore safety and sanity to America.
