While all that is possible it is also trivial to work around. No download can take place without an outgoing TCP connection and "upload" of a request. Therefore all desired uploads can simply be inserted or steg'd into requests depending on the efficiency tradeoff. As for blocking sites, talk to the Chinese, then talk to the people who work around the crap that the Chinese do. It is a fair amount of work and an arms race, but the information access side always wins unless the internet is completely turned off.

Understood on all that...I was just pointing out the possibilities. The Chinese face this everyday and have had time to form contingencies...the average citizen in the Ferguson area probably just says "Oh $hit, the internet is down", and goes about their day dodging the zombies.

True for a day or two. After that someone somewhere in the world writes an app to get around the blocking and then everyone downloads it. The trick is finding out about the app. Normal ways of geting it (links from facebook) might be blocked.
