Again, bowling OVER and AROUND the wicket is not relevant. The only thing that matters is that the ball must not pitch outside the leg stump. An offspinner could ball AROUND the wicket, have the ball pitch in line with the stumps and get an LBW. A legspinner could ball AROUND the wicket to a left-hander and easily get LBWs. Wasim Akram used to bowl AROUND the wicket to right-handers and get LBWs. Again, the ball must pitch either in line with the stumps or outside the off stump.
