I stated it as a recollection, not a "claim."
Many FReepers have been working hard to find out what is being found and where it came from.
Anybody who has such sources would be VERY unlikely to divulge them, because the people in a position to know would take a very dim view of such a revelation.
IOWs there is no reliable information, from any source, as to what the drug gangs have or where they are getting it. We have your recollection, from an apparently unremembered source, that something other than M-16s are the most found drug gang weapon. A "recollection" I did not tacitly disagree with.
You have danced around every question I have put to you and all the supporting information I have produced so I don't really know what point it is you're trying to make. The bottom line is the drug gangs aren't getting much from gun shops, gun shows or any other civilian source in the U.S.
