The Second Amendment Foundation has filed an amicus-curiae brief in the Bean case, which has been granted certiori before the United States Supreme Court.
The case involves a man who travelled to Mexico, accidentally had a small amount of ammunition in his vehicle, and was convicted of trying to smuggle said ammunition into Mexico in a Mexican court. He was imprisoned briefly in Mexico and then returned to the United States to serve the rest of his sentence.
Because his crime was considered a felony in Mexico, he was considered a prohibited person in the US (no firearms rights), even though his "crime" is perfectly legal in the US. Bean petitioned the BATF for restoration of his firearms rights on those grounds, and was denied, because Congress provides no funding.
So he filed a lawsuit, which has now made it to the Supreme Court. This is an opportunity for the SC to speak to the 2nd Amendment (which is not without risk!), but seems an excellent case on which to do so.
