One would hope it is also laughable because we have constitutional rights. Singapore does not.
Singapore also practices corporal punishment. In the end, your penalty is lashes. So there isn't much of an appeal process. In addition, if you are old/young, rich/poor, crazy/sane you all share in the feel of the lash consistently. There aren't people that are willing to live with the consequences of their crime.
When I was there, you could eat off the floor of their subways. (the trains, not the restaurants). In some ways, I am envious, in others it is barbaric. But if you are Bill Gates or some kid on East 55th in CLE, when you get five lashes, you've been punished. You don't get the Martha Stewart treatment.
