I'll respond to you the same way you responded to me.
"That's literally a violation of the constitution"
The phrase "cruel and unusual punishment" is an abstract/arbitrary/relative phrase that means different things to different people. What one team of nine justices calls "cruel and unusual" can easily be ruled constitutional by another team of nine justices.
"There's a reason we don't execute 10-year-olds even if they kill somebody. Because their brain hasn't developed enough to understand the consequences of what they are doing"
Not all ten-year-old brains are alike. Not all ten-year-old kids commit murder either. Educational psychologist Jane M. Healy, author of "Endangered Minds" and "Failure to Connect" says brains are physically shaped by experience. So the more you use a certain portion of your brain, the faster it develops. Brain development is measured using MRI scans, but less than 2% of the global population receives an MRI scan in a calendar year. So I'm sure there's a few people whose brains have fully developed several years ahead of schedule because they had great parents to help them in the process. If parents knew that their children could be sentenced to death for their crimes, that would undoubtedly motivate them to become better parents.
"You think fast cars make a city safer? How so?"
If fast police cars don't make a city safer, what does? You tell me.
"Why would Chicago cops want to chase someone to Ohio or Iowa?"
I'm not saying police chases should last that long, I'm just saying that the Chicago Police Department for instance, should not be mandated to give up as soon as the fleeing suspect crosses the city boundary. Now if one police department can pass the buck to neighboring police departments and that gets the job done, fine. Just give me a link to an example where that worked.
