I guess I'm just curious..

Since January 1, 2024, my boyfriend has been in prison, and in July he transitioned from county jail to a state facility. Since that time, I have occasionally received notifications from the state indicating that his messages were not delivered due to policy violations. During our recent phone conversations, he expressed his curiosity about why I never replied to his messages where he voiced his concerns about the medical staff, policies, and procedures. Regardless of the specifics, I don't see any reason why those emails should have been blocked. Although I haven't seen the contents, I find it hard to believe that allowing those emails would pose any risk to the department. The emails were simply expressions of non-threatening medical concerns, without any corruption or conspiracy. Also on March 5 he called me to tell me he was in the box and that he doesn't remember what happened.  He said that he was in the box and the last thing that he remembers is going to bed.  The report given to him claims that at around 3 am he was in his cell yelling out. The C.O. claims that my boyfriend assaulted him by punching him though he had no marks on his hands nor did they feel as though they had made forceful contact with anyone or anything at all. To my understanding whether there was contact with an officer or not any incident that requires the removal of an inmate is considered an assault.  Since then I have personally spoken to a 3rd party that was in contact with an inmate who witnessed the situation and he stated that my boyfriend never hit anyone.  All he was doing was yelling and the officer's carried him out by his pants and shirt.  Now I'm not saying an officer's job is not hard nor am I making light of the fact that there was an incident at all.  I give credit where it's due no matter who it is or what they do and I'd like to understand what happens now and what is to come.  I've looked it up and maybe I just haven't found the information yet though I would like to know how long it is supposed to be before there is a hearing and if they surpass the date does that deem the case dismissed? Also, due to the severity of recent events in New York I was under the impression that whenever a corrections officer is on duty they're supposed to have a body camera on so what happens when there is a supposed situation but there's not been any camera footage to clarify what actually happened?
