Gan wants L.T.'s kind of strength. The kind that if you had half a brain, you'd know just by looking at him that you shouldn't fight him.
Besides, we all feel like we want to punch someone sometimes just because they annoy the heck out of us but not in the society as it is today. We can't give someone their well-deserved beatdown because they'll run and cry to whoever that they are being beaten and then they'll try to sue us for whatever bone-headed reason (Yes, I've had to deal with this before - it makes one put off learning martial arts in the first place). But certain types of people will abuse power in whatever form they can get it in - which makes it harder to get to those people because of all the rules and laws and whatnot around them.
