Read this wonderful interview with him at Street Art NYC:
Like a fool, the first pole piece I ever put up almost got me busted. I didn't even slide the bolt completely in when this cop car comes whipping around the corner and out rolls T.J. Hooker. He asked what the hell I was doing to which I quickly replied, "I'm taking this lovely piece of art down because I just had to own it for myself." After his brow-beating, I suggested I'd put the work back "where I found it" (wink, wink) to which he replied, "Yeah. You do that." So at this point, I'm standing there bolting in my art while two cops made sure I did so. People are passing by looking at me as if to say, "Do you not see these two cops next to you?" My friend later called it "sanctioned street art".
