We are only guessing, but it sounds like in might be in disciplinary segregation, also known as the SHU. The Special Housing Unit is isolated from the general population. Inmates are put in the SHU for various reasons, none of them particularly positive sorry to say. He will be allowed incoming mail, magazines, photos, books... but limited commissary and phone 

Well, for one, he is in prison and in prison the guards are there to keep order. If an inmate is out of order and can't behave while locked up, they will isolate them away from the general population. If they continue to act out, they will do their time in solitary - this is hard time, emotionally. He will not get caught up in anything that will get him hurt because he will be away from any conflict while

It is segregated housing within the facility. It is used for disciplinary or administrative segregation from the general population.

When an inmate begins their sentence they are given "good time" or "gain time" of 15%. Therefore the inmate is set to do 85% of their sentence. If they get into situations where incident reports mount up, they could ultimately have their good time taken away. Discipline cannot add time to their sentence unless a new crime (assault, escape, attempted murder, murder) was committed and they were found guilty.

Nevada Southern Detention Center is a CCA facility which means it is privately run. I've been in a CCA prison in Tennessee which could not have been more strict. The CCA staff follows the rules to the letter. In my opinion, when the guards stick to the rules (on the strict side) there are a lot less problems. The inmates take the position that it's not worth going to the SHU because there are no second chances to avoid punishment.

Inmates do not have access to the Internet. There are some facilities that now have an email service that is closed from the Internett. However, the emails cost the inmate to read and write. Even though inmates do not have online access, and therefore no Facebook, but we know for certain that inmates get ahold of smartphones and can create and maintain FB accounts. Not smart, but they figure they are in prison anyway, why not break more rules. We

Probably not, but depending on the severity of the charge that sent him there is certainly could delay things, we'll have to wait and see.

Yes. Inmates in solitary confinement for disciplinary or administrative reasons are allowed to have mail like the rest of the institution. Mail is considered sacred by the prison administration, they do everything in their power to ensure the inmates remain in contact with their families and loved ones. There is a caveat, if the inmate is on a terror list or has committed a terror act, the courts have restricted outside contact in some cases (see Boston bomber convicted terrorist).

Yes they do, unless they are serving sentences subject to disciplinary time imposed.

Don't panic, there is probably a logical reason for it. We do not have that information, try calling the facility and speak to the "captain"
