Redline

Here's the thing, we still don't have HD video of Assad tossing the canisters of nerve gas in Syria. No DNA evidence, fingerprints, ditto.

Plus, we don't know if this might have been a reaction to an anti-Islamic video.  (for which we are so terribly sorry) Just, you know, people out for a walk encountering a protest, and they just happened to have chemical weapons...

So anyway, at this point all we can say is that a line, that may have been red, may have been crossed. But at this late date... What difference does it make?
