Short and direct explanation of prison abolition. Prisons don't solve the problems or repair harm, they only add to it. Angels Davis will encourage you to imagine a different, more positive way (and stop the demand for a one to one substitution). 

I love and agree wholeheartedly with her emphasis on this point:
"Alternatives that fail to address racism, male dominance, homophobia, class bias, and other structures of domination will not, in the final analysis, will not decrease decarceration and will not advance thre goal of abolition."
