Not on topic, but I volunteered for a study a couple years ago, for the benefit of understanding the plight of paraplegic people. I had a nerve block catheter placed in my left leg, which completely numbed and paralyzed my left leg and foot, for 6 hours. I got to feel exactly what it's like to see and touch my leg, but have it as basically a dead-weight ball & chain to drag around. I tried crutches, and even a brace to mimic a fake leg, and it was a very eye-opening experience. On another day, they put it in my right armpit, which did the same thing; arm just hanging there totally useless. learned to drive with only my left arm, and even things like taking a leak were very difficult. It was kind of scary because I had to "trust" that the leg and arm would come back to life after the catheter was out, and it did of course.
I think the paralysis penalty is a good one, but I'd only stand behind it if it were done on a temporary and reversible basis, in case the criminal pays his/her debt to society and deserves to get the use of the limbs back again (obviously only in cases where the temporary punishment fits the crime, of course). If the crime caused permanent paralysis, then let it be permanent.
