There's no perfect solution. In Alabama, they put a cap of three times actual damages for punitive damages. Of course, this is the state (in)famous for the bad BMW paint job $70,000,000 lawsuit. Three times actual damages is, in my opinion, too low, but I wouldn't have a problem with up to ten at the judge's discretion.
Also, I would be in favor of the state having doctors on some sort of retainer to give an unbiased opinion of someone's physical state.
"Purgatory's kind of like the in-betweeny one. You weren't really shit, but you weren't all that great either. Like Tottenham."
I'll try being nicer...if you'll try being smarter.
