The Secure Housing Units (SHUs) are also known as solitary confinement which is an isolation ward that mostly is located separately from the main cell blocks in the prison. When an inmate is in SHU, he is locked for 24 hours a day and meals are delivered through a slot in the door for security purposes. (Solitary Watch) The Purpose of the SHU is to prevent contact with other inmates in other to punish for any disobedience or aggressiveness of an inmate towards other inmates or prison officials. But I do not think it helps reduce any gang related activity within and outside the prison facility in the long run reason being that gang members do have like hierarchy and there is always a chain of command, it is just like a corporate organization but in this case status are earned through violence or theft or instructions to murder another opposing gang. So, if a gang leader is housed in one of this units for days does not mean the gang related codes and rules will be discarded by the remaining gang members who are not housed. To mean it just creates more avenue or reason for more violence to be perpetrated when they are eventually released.
