He was a liability, sarcasm...we all know Lee is an uncontrolable monster OUTLAW so it didn't make sense economically and legally to have him compete with the risk of having him dye his hair a funny color or get a new tattoo or saying something "shocking". They just couldn't take that chance...imagine what would happen if he would have flipped someone the bird? Whew! All of Las Vegas would have been shut down...
So you are saying that if Lee spoke his mind, it would have had the same effect as Ernest Scribblers feared invention during WWII?"Wenn ist das Nunstück git und Slotermeyer? Ja! ... Beiherhund das Oder die Flipperwaldt gersput."
