I've read that article. I think it's misguided. I've actually written to the author and provided some statistics. I think this is a red herring. I don't think it's based on facts.
The reality is that if you are indigenous in our system, in federal corrections, you're more likely to be released later in your sentence, you're more likely to be subjected to use of force, you're more likely to be self-harming and you're more likely to have your parole suspended or revoked. There is no real benefit in declaring yourself indigenous. The statistics that I provided to that reporter show that there has not been a wild increase. There may be some cases of abuse, but certainly nothing systemic that I could see from the numbers.
