Around 40% of the prison population is there for violent crime. And for most, it's probably a very loose definition of "violent". Few would argue that you shouldn't put violent offenders in prison, but that's not the reason the majority of people are there.
Does this mean you think any criminal (that committed a violent crime) should be locked up for life? Or how does the length of prison sentences factor into this?
That's right. And that's why we put people who do things like smoke the devils lettuce or sniff a little columbian snow in there. To keep these menaces away from the rest of us.
I mean, can you imagine? People just walking around doing what they please to their own bodies and not providing slave labor to the state or private prison corporations? The absolute horror!
