Back at the beginning of last November, I bought a handgun and applied to the state of New Jersey for permission to take it home. After two fees and two and a half months, the State Police finished their background check which, going by how long it took, must have been heroically thorough. I got the call this morning that my pistol permit was ready and (as I don't work on Mondays) swung by the PD to pick it up, and from there on to the sporting goods store to get my new firearm. I gave the clerk my new pistol permit, my NJ Firearms ID (which required another months-long background check to get), and my receipt for the purchase.
Unfortunately, it turns out that the federally-required "instant" background check system is closed for the holiday. So, because background check number three couldn't be completed, my new firearm is sleeping in the gun shop's safe for one more night.
Sorry, you can't exercise a Constitutionally protected civil right because it's Martin Luther King day.
