Realist, you keep forgetting:
#1. The US has the death penalty and Texas has the highest rate of *clearing out old cases*. Whether or not you agree with it.
#2. As TresHappy pointed out, no matter what everyone is saying, she is not being tried for capital murder which would be a death penalty case. She could get 30 years max. That means with good behaviour and becoming born again, she will be out in 10-15.
#3. Most people in the US say "Fry them", "Hang them", "Cook Them" and various other terms to indicate the level of justice a person feels an offender should receive. The offender very rarely receives the level of justice the general public would inflict. The laws don't allow for it.
These are common responses from people living in America who see a terrible crime and want the person responsible to feel the pain the victim must have. Though with lethal injection, it is like being put under for surgery.
No matter what your stance on the death penalty is, this is not a death penalty case.
Justice takes so long and is uneven here in America, that we take out our frustration with phrases like those. (at least that is my theory-that is what I do)
