Spousal abuse is rarely a first degree crime. People don't plan to harm their spouse, it is an act of spontaneity that is programmed by our upbringing. Shoplifting is up in the air, but usually done by minors too. Minors can be excluded from adult sentencing. Besides, shoplifting is usually spontaneous, and not a first degree crime under such cir stances.
You are thinking like a democrat, thinking raising taxes raises revenue. With enough warning, people will curtail their actions.
First degree crimes are planned crimes. Do you really think that the crime rate of such crimes will remain constant, that someone who plans to kill, steal, etc. will not take the death sentence into account?
I would expect very few overload if any, needing to commute. Maybe at first all should be commuted for like the first 90 days or so once the law is effective with a second time the kicker?
Oh… serious crimes would not be commuted.
