Let's not "drone" on about Fast and Furious. Still another example of why government is not reason. "Hey! Let's limit the flow of guns into the hands of Mexican drug cartels by selling them to those very same people!"
But here's the real story: Careful when you sell your firearms, legally, and you were the original purchaser.
Along with a number of Caribbean police forces, many countries use eTrace software:[7] Mexico, Colombia, Suriname, Tobago, Guyana, Canada, Germany, Bahama, Jamaica, Dominican Republic, Barbados, Anguilla, Antigua, Barbuda, Aruba, Curacao, Dominica, Grenada, St. Vincent, Grenadines, St. Lucia, Belize, Costa Rica, El Salvador, Guatemala, Panama, St. Kitts, Nevis, Britain, Australia, Japan, and Belgium.
These countries have access to American gun owner identities and information (first purchaser only) as a result of traces of recovered firearms contained in the database.[12][13] In GAO Report 09-709, ATF reports the National Tracing Center, “conducts the gun traces, and returns information on their findings to the submitting party”.[8]
