ATF Sends Ironic Letter to Licensed Dealers

The Bureau of Alcohol, Tobacco, Firearms, and Explosives (ATF) have sent out a letter to federally licensed firearms dealers to keep a look out for terrorist trying to buy firearms:

While the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) has received no specific threat information associated with the anniversary, we encourage you to exercise increased awareness and vigilance as the anniversary approaches. The security of your business operations, particularly your firearms inventory, is very important; and you should heighten your security precautions in light of this upcoming anniversary.

I wonder if you’re supposed to inform the ATF agent who is forcing you to sell the firearm to the suspicious person or if you’re required to go through the red tape of submitting a formal report.
