Do you have any evidence that Ciancia did not walk up to a checkpoint, pull a rifle out of a bag, and start shooting, or is this some sort of knee jerk "If the media says something it must be a cover-up and this is necessarily a false flag attack because ancient aliens and the bible code" reaction?
Maybe it's just a natural reaction to these two things;
1. They never seem to actually know what's going on (see all recent shootings).
2. Their penchant for spinning everything.
the default is to assume you are being fed a load of crap, because that's what usually happens. I agree with Mike; the burden of proof is on the media to prove they actually reported the truth and not some made up BS.
