Surely bad facts by media can make it look fishy (or conversely, mask other real fishiness). That aside, I don't care what kind of conspiracy theorist label you slap on me, we should always keep our eyes on our government. The forefathers warned us of government ("a necessary evil") and told us to never trust it. A proper government should run under careful scrutiny and constant examination at every level.
The facebook page thing was supposedly an older page that was renamed (likely true). The google cache stuff is fishy, could go either way with the explanation. There's some video footage of people acting differently than you might expect (laughing, etc). Nothing necessarily consequential. There was some tweet that was put off a week early that I don't know much about. There's also something about FEMA training that was weird, that also occurred with other incidents (like CO and 9/11). Didn't look further into the validity of that.
I wish the government were more interested in liberty. Then I wouldn't give this a second thought.
