Yeah, this is pretty much a wash.
Some states have the death penalty and some don’t. Michigan has not had it since 1846. It is up to the residents of that state to decide if they wish to deal with the increased costs of incarceration and/or higher crime rates.
—Wisconsin is another one—no death penalty since statehood in 1848-—and had a near negligible homicide rate until Chicagoans started self-importing due to lax welfare laws—
Washington State Supreme Court has just declared that the lives of capital criminal are more valuable than their citizens.
Back in the day when rapists were subjected to capital punishment (real rapists, not just the accused), society rightly decided that this needed to be dailed down because it could put the victim's life in jeporday since the perp might feel there was nothing further to lose and he would be less likely to get caught if he added murder to rape.
That's not the case here. The Washington Supremes have declared that no matter how many of our citizens you murder in whatever vicious manner, we still won't kill you back.
The legislature should make that declaration if they have the votes to do so.
