There really is no explanation. ..... Just makes no sense what so ever. It's not like they go into a deeper background check for a can than a firearm. Although speaking from experience the government is altogether slow at everything. I should know. I worked 20yrs for the federal government and retired and shit was always slow. Now I work for the State and shit is even slower to get stuff done. No matter how fast you try to process stuff. For some reason the system is just set up with so much inefficiency that it's hard to get anything done in a timely manner. Hell just 10 years ago they started to finally make progress in the processes of things only to be slowed down by outdated systems.... That is where they should of started first... don't ya think. Looks like six sigma may need to be called Into action to see the uselessness there is in all that the government does. Or maybe they just don't really want to see how screwed up it really is. ... lol.
