Friday Night “Fast & Furious” Document Dump, and Obama’s Great Compromise
Now it turns out that two of the “big fish” supposedly targeted in the bungled “Fast & Furious” ATF weapons export program were FBI informants. And their status as such made them essentially “unindictable” by the Federal Government. Well, what did you expect? Did you think that the Reichstag was going to torch itself?
Brings up a nice point: has any Republican in Congress uttered the phrase "Reichstag fire" yet? If not, why not? It's not as though the Democrats were hesitant to throw rhetorical bombs, and in this case the bomb's not all that rhetorical.
