Hello again, my inmate is in Rikers island jail but it's the third time they have moved him to another building, why do they move him all the time?

There are many reasons that inmates are moved. Most of the time it is nothing to be concerned with. There are changes in the inmate population which require movement and aligning certain inmates with the same classification type based upon the criminal history, violence associated with their crime and length of sentence. Many times, the inmate gets their custody level changed for the better - calling "working your way down" as in the type of housing and security.
