I think this squirt assault on Cruise was a setup – by Mr. Cruise.
See, there’s been all this press lately about how unhinged he is. So what better way to turn it around than show how calm he can remain facing down a four man crew after being assaulted. Notice how well it was filmed, and how clear the audio was? Notice the absence of Cruise’s security retinue that allows this to go one for what seemed like a couple of minutes.
