Hopefully his hands are connected to a shackle around his waist.
I bet you're right. Makes me feel a little better for the safety of his guards. Do you see that skinny chain connecting his feet? I want to see a huge chain there. In fact, I'd like to see him shackled like that guy in Silence of the Lambs. This guy is one big bad dude. I never realized how dangerous being a prison guard can be.
