NRA-ILA has recently received several calls from NRA members in border states who have been visited or called by agents of the Bureau of Alcohol, Tobacco, Firearms and Explosives. In some cases, agents have asked to enter these people's homes, and requested serial numbers of all firearms the members possess.
In each case, the agents were making inquiries based on the number of firearms these NRA members had recently bought, and in some cases the agents said they were asking because the members had bought types of guns that are frequently recovered in Mexico.
Read it all. And wonder, as the man says, just where the list came from?
