For days, months or even years, those convicted of certain crimes may find themselves locked up in isolation, better known as solitary confinement.
 
Some are pushing new legislation in New York State that would change what goes on inside New York prisons.
 
A petition drive is underway backing legislation that would remove the mentally ill from ever serving in confinement, limit time inside to 15 days at once and create rehab centers instead of isolated confinement cells that are about nine feet long and six feet wide.
 
Advocates of the bill estimate that nationwide there are about five thousand people being held in the cells.
