It's a great article that shows exactly why the program is a failure (2% of all denied persons were arrested) and explains how truly pointless background checks are. It's basically a system to keep the honest honest and deter those criminals too stupid to avoid a gun store.
Yet here is the best quote and the summation of all background check schemes: "Washington voters are now facing a ballot measure that will expand this failed system to private transfers. Nevada is following their lead. We will almost certainly face a similar measure here. Make no mistake, background checks are gun registration schemes. Efforts to expand them are being funded by billionaires with armed guards."
Don't sign the worthless universal background check petition going around and don't vote away your rights.
