How about safety for Black people and other citizens from state sanctioned extra judicial killings by thugs in uniform? The existence of prisons has not deterred cops from killing citizens at the rate of almost three per day - you've been seeing the news of Black people being killed by cops hands up on their knees or in front of their own children. Not to mention the corporate law-breakers who aren't even charged - do you know of anyone from the 2008 banking and real estate law-breaking who has been charged, let alone served time? So, if you are in favor of prisons, advocate for throwing the true mega-impact criminals in there. Or abolish the prisons so racists don't have an excuse for going after the lives of Black people.
As far your scary-monster rapists go: “When people tell me, ’What are we going to do with all the rapists?’ I'm like, ’What are we doing with them now?’ ... They live everywhere. They're in your community, they're on TV being outed every single day.... You think that that system is doing a deterrent thing that it's actually not doing.” Abolitionist and educator Mariame Kaba to MSNBC’s Chris Hayes, quoted in Teen Vogue. https://www.teenvogue.com/story/what-is-prison-abolition-movement Even you can learn from teenage girls. Or perhaps you can't.
