The guy may be a sleezeball---but its still the way the justice system is supposed to work---it was not his DNA under Jon Benet's fingernails---the reason to arrest an extradite him in the first place---but actually the Colorado prosecutors acted fairly responsibly as the publicity blew this way out of proportion---and so he was arrested somewhere else by a publicity hound who had no case.
Lesson to be learned---don't try your case in the supermarket tabloids.---or too many people will get wrongly convicted.
