A bank robbery has occurred Two armed men
A bank robbery has occurred. Two armed men have been apprehended In the vicinity of the bank. Pamela Leutwyler
The district attorney does not have enough evidence to convict either man of the armed robbery - UNLESS ONE OF THEM CONFESSES. If neither one confesses, the most the district attorney can do is to sentence each one to 1 year in jail for illegal possession of firearms. The men are separated. Each is offered the following deal: If you confess and your partner does not confess, you will go free and he will be sentenced to 10 years in jail. If you both confess each will get a reduced Sentence of 5 years in jail. If neither confesses each will get a sentence of 1 year.
