Its too late for that. Look to the future instead. Will having Arron's Law in place, coupled with civil outcry and petitions we've seen , prevent the next Aaron from being over-zealously prosecuted?

I think the answer is: not entirely, but its a huge, practical step in that direction. This is one of those things that you celebrate, not dismiss cynically.

Think of an alternate reaction. Why not create a petition on the whitehouse to make this small step a reality instead of cynically dismissing it? Remember, your pessimism can influence a whole audience into inaction. Recent precedent suggests.
