One could easily turn it into the fact that authorities aren't doing their job properly, without the conspiracy notion, just like 911.

But then again the catch 22 is that they'd request another oversight commission along the lines of DHS, BATF, TSA, FBI, or CIA to really corrupt and paste things over into a real conspiracy along the lines of Project Gunrunner and such expansions of BATF into all encompassing FATF or individual SATFAs.
