Someone once told me that a machine gun is the best insurance for your gun collection in case of theft. If someone shoots a full auto within earshot its likely to raise suspicion and a call to the local officials. They'll get in touch with the state and federal officials. All the extra law enforcement will find the machine gun, find out where it came from and eventually find the rest of your collection. Maybe even your TV and jewerly too. Does any of that seem plausible?
