How will they know who's doing it? Like I said, there's always TOR and proxies and all that fun stuff. Officially, Chinese people can't blog freely or access the whole internet but that doesn't mean they ACTUALLY can't. Trust me, they do, I've seen it. The government can't fine you if they don't know you're the author.
And yes I think the government is more afraid of cameras than guns. They can deal with a gun. Using violence is one of the only things they are good at. But more and more people have cameras on them these days in the form of smart phones. Many of them upload the videos directly to the internet so their's no tape to destroy. Go ahead and smash my phone officer, the video already has 300 views on youtube. Yes I think the government is more afraid of bloggers with cameras than they are with gun owners, and I personally own 12 guns and have open carried hand guns in public. I'm the biggest pro-gun person you'll ever meet. But if we use them, or threaten to use them against the government, even in self defense, it is easy for them to paint us as the bad guy. But with a camera, it's obvious who the bad guy is. Even in some distopian future where it is obvious that using violence in self defense against the government is warranted, if you kill one jack booted thug, 10 more will show up and you will end up dead. It's more effective to destroy their image. They rely upon positive public perception to maintain the status quo. If you destroy their cloak of legitimacy and most people see them for what they really are, there's nothing they can do. They know that and that's why they fear bloggers with cameras more than they fear gun owners. Besides, gun owners are just posturing when they say "from my cold dead hands". When they JBTs come for your guns, you'll turn them in and so will everyone else. Maybe a few shots will be fired but not from you or me. It'll be some guy out in the boonies who they will quickly kill and then paint as a whack-job. The most that any gun owners will do is bury a few guns and then tell the officer that they dropped it in a lake on a hunting trip.
