That's the point I have a problem with. I don't believe that most people will lose a minute's sleep, much less qualify as "tortured". Thus, the PSA would be making them a liar in addition to a murderer.
Go find one of these tortured souls and ask them if they have made any attempt to improve their driving skills, such as attending a non-mandated class, since the incident. You know, because they might want to prevent it from happening again? Good luck finding one.
