To be honest, she didn't get 70 years for stealing power tools, she got 70 years for being a career criminal with multiple arrests and convictions.
The power tools were just the latest and last of a long line.
IF she had broke into my house, the castle law allows me to put her down. I see no reason why the state can't do the same. If you commit a crime
against a person, and the law allows that person to use lethal force against you for that crime, then the state's punishment for the crime should be
the same.
