The "Gun Show Loophole" as presented by McCain and others has nothing to do with the illegal sale of guns. The real loophole is a financial one. The vast majority of gun sales at shows are for cash and therefore untracable and unreported today. The Government(s) whose need for money is insatiable would like to close this loophole and reap the tax rewards. The item buried in the Obamacare bill is an attempt to close this loophole.
