James Kilgore is a writer, researcher and educator at the university level, and a man who spent some years locked in a high security prison. Because of the experience and seeing the disproportionate numbers of minorities being imprisoned, he has written: Understanding Mass Incarceration--A People's Guide to the Key Civil Rights Struggle of Our Time". Since 2002, the US has had the highest incarceration rate in the world, with 500 prisoners per 100,000 residents, or about 1.6 million prisoners in 2010, about 5 times higher than other countries of similar size, with high incarceration rates. With this being the weekend that honors the life and legacy of the Rev. Dr. Martin Luther King Jr, this connects with his stance on social justice.
