"A Billings man in prison for drug possession has filed a $10 million federal lawsuit against Yellowstone County for alleged civil-rights violations, including interference with his satanic religious practices."

Such artfully-written works of fiction surface from time to time (in this case, on the Drudge Report website) to refresh our brainwashing about Satanism. They contain so many lies that I can't hope to address them all.
First of all, Satanism/SRA IS a crime against humanity, and in extreme cases it resembles war-crimes sprees, such as the US/UK/Israeli "war on terror." A major part of our system of "justice" was erected specifically to protect Satanists from being arrested, charged, or prosecuted for their "religious practices." For example, consider what Alberto Gonzales did while he was the highest law-enforcement official in the country: he defined certain war-crimes, which just happen to be useful as forms of SRA, to be legal activity.
Secondly, many prison guards are Satanists ("Israel" is a prime example of this), because the job affords them with many opportunities to "practice their religion" in the guise of maintaining prison order. There are many similarities between the abuses inflicted upon prisoners in the "war on terror," and those inflicted upon prisoners in US civilian prisons. Some prison guards in US civilian prisons ended up as guards in prisons set up as part of the "war on terror."
If a Satanist does end up in prison because his crimes are too egregious to be swept under the rug, there is no reason he cannot continue his "religious practices" while in prison, as long as they are kept within certain bounds. Prisons are by their nature full of nasty characters who treat each other cruelly, although typically due to selfish motives or psychopathy, as opposed to purely evil motives such as the belief that one is being prepared for initiation into black magic, which is the greatest possible crime.
But it could be more difficult to conduct SRA in prison because it might be harder for a Satanist to find an innocent person who doesn't "deserve" to be treated cruelly. (Being cruel toward people or animals who are "innocent" or helpless magnifies the conscience-destroying effects of SRA.) Perhaps the notion that being incarcerated interferes with Satanic "worship" is actually hinting at this.
The notion that he was being abused while in prison doesn't seem plausible. If he was a Satanist, he wouldn't be abused by other Satanists (one of the privileges of being a Satanist), and he wouldn't be abused by the Christians who were supposedly encouraging him to "get saved." This claim strikes me as a deliberate attempt to dissociate Satanism from the pedestrian, non-ceremonial sort of abuse which actually comprises SRA.
