Mexico has some very tough gun laws, as anyone who has seen news reports about some hapless American who accidentally took a shotgun down there knows. But those stringent gun laws only serve to make the honest citizens helpless against the armed gang members.
Anyway, in this video clip at the Phoenix CBS news website KPHO.com the reporter says Mexico's congress voted to ask the U.S. Senate to create a registry of all commercialized firearms in U.S. border states to make it easier to trace guns used in violent attacks there.
Some of the more reactionary websites are assuming the Mexican government expects to get the list for themselves. Examples here, here, here and here. But to be fair, they all refer to the same KPHO.com video which says only that Mexico wants the U.S. Senate to create the list, not that Mexican politicians want it for themselves.
There are some law enforcement reports from time to time about real gun smuggling into Mexico, but since the borders are supposed to be so secure, one has to assume those are rare. The real problem was the U.S. government's involvement in the Fast and Furious operation through which guns were allowed to be sold to smugglers and taken into Mexico.
Atty Gen Eric Holder and President Obama got a free pass on that one. To those Senators considering Mexico's request, you need to refocus and find out what Holder and Obama knew about Fast and Furious and when they knew it.
