So as someone who is a tard wrangler at a group home, and a follower of christory since about 2011, allow me to explain some of the other things he may get annoyed with based on what I have seen working several facilities.
Limited to no internet access: No ability to watch the shows he wants or if he can, only for limited intervals (strictly enforced), no porn (also strictly enforced), and heavily restricted access to social media (usually only if you behave, although all facilities are different).
The amount of "slow in the mind" people he will be around: lets be honest here, Chris has been vocal in the past that he views himself as better than other people with autism (and maybe down syndrome). Imagine Chris in a home where he had to deal with individuals with down syndrome, autism, schizophrenia, and various other mental or developmental (there is a difference based on diagnosis) disabilities. Now imagine him living there for up to 5 years. It was posted in his jail letter that he may have tried to perform an exorcism on someone while at the mental hospital under heavier guard, now picture that at a group home which can have as few as one staff to ten residents.
Roommates: the facility I currently work at sleeps two residents to a room. Just picture Chris getting put with someone with lower functioning autism than him, who doesn't buy into the merge, or just rages even more than Chris does, or, well, any other number of reasons.
Food: at my facility, they may get some type of fast food (or any type of restaurant food) once a month. The rest is government approved sodexo/sysco/whoever the lowest bidder is, food that I would consider worse than what I got in all the MREs I've eaten (vomlet excluded). Although, knowing Chris, he may actually appreciate the TVP, as its mostly soy, so this could potentially be a plus.
Communication: while I am not sure what group homes are like in Virginia, where I work, communication is heavily restricted. Monitored calls to prevent asking for things that they can't have, monitored outgoing mail (there's a story to why that happened), as well as incoming mail so that no contraband gets in. Obviously this would prevent Chris from begging as much (although to quote Jeff Goldblum "life finds a way") if the screen them, but I have no way of knowing if they would actually screen his letters at whatever facility he goes to, however, if any of his letters are brought up in trial, they might.
Feel free to address any questions and or concerns, and I'll respond to the best of my knowledge.
