I was thinking the exact same thing as I watched. It seemed ridiculous that any of that was needed, but I was like "I bet those cops are having a blast!". Hell, it made me want to strap on the kevlar and go kick a few doors in.
More seriously, it was interesting to hear Dotcom say he (smartly) decided to let the cops find HIM rather than go to them as he didn't want to startle them and get shot or something.
Don't underestimate the impact of this simple truth.
