As the US always boasts about its dental care why do thier serial killers always have crooked teeth ?

No cheeky answers or I will be over the there to kick some butt!!
--------------------
Why is this even a topic of discussioN?? Dental care is not like medical care - not everyone has it. It seems that you almost have to be middle class now to even be able to get dental care. Plus these guys in prison might never had dental care before, why give it to them now? No way should a serial killer have better teeth than the common man. Sure fix their absesses (?), cavities, etc. - but don't whiten their teeth or straighten them!
