They are going to make Tiananmen Square look like a joke.

I don't think they can do that at this point.

There's a camera in every pocket and the memory cards are so small that they can be hidden literally anywhere. Even if they shut down the entire country's internet, there's NO suppressing the pictures and videos that would be taken.

Look at Hong Kong for how this is going to play out. Rubber bullets, beanbags, tear gas, lots of arrests over weeks and weeks until the protesters get tired and remember they have to eat and sleep and pay bills.
