Police officers, fire fighters and other emergency personnel also risk their lives and see their friends lose partners and friends of their own, and are also tasked with protecting our way of life, and they are allowed to walk away from the job whenever they decide it's time.

I respect the sacrifice our military personnel make and my mother served 20 years in the Air Force.  I still believe they should have the right to make their own decision about when it's time to quit and not face jail time.  It's the very fact that they have experienced the horrors you talk about that makes me believe this.  Nobody should be subjected to those events and be forced to continue their line of work.
