So, do you think every person who kills should be in prison for life?  What about causing accidental death, say in an RTA?  Or death by negligance, rather than intention?

To have that many lifers in the system would break it.  This teen may live to be 85 or more.  That would be 70 yrs.  Think of the cost.

If a person is no longer a threat, surely it is better they be reintegrated?
