Please understand that there are too many responses to read every one. So, I don't say this as a Eureka moment for anyone other than myself. More or less talking out loud.
The idea that they moved RA for his safety has just been an almost nothing clue for me, thinking they moved him because they were afraid of what an angry mob might do, but after a few days of reading around, and wondering about Carter saying that "today is not the day", I now think they are protecting him from whoever else might be involved, which may be more than I suspected.
