Twelve years ago yesterday, Timothy McVeigh used ammonium nitrate -- simple fertilizer -- to blow up the Murrah Federal Building in Oklahoma City, and kill 168 people in the process.

But despite all those deaths, and that time gone by, Congress still can't get its act together to come up with a way to screen folks who want to buy this terrorist munition of choice, ABC News reports.
Meanwhile -- thank God! -- "the National Rifle Association and top Democrats have opened a dialogue about how to
beef up the database that gun vendors use to check a potential buyer's criminal and mental health background." But given how long it's taken to get these fertilizer-checks straight, I'm not about to hold my breath.
