I know you don't mean to sound this way, but your comments come off in very bad taste -- we're talking about the murder of a 16-year old girl. There's nothing positive that this country needs to "learn" from Iran.
I am sorry if you think that this country is above all the others in respect to morality and right and wrong. It certainly doesn't take a genius to spot the flaws in our society. Just look at our prisons and crime rate. We need to learn from someone because we certainly aren't doing the job.
