Six Federal Inmates plead guilty for having prison weapons

Six Federal, Inmates, in federal prison in West Virginia, plead guilty to having homemade prison, weapons or shanks as they are called.

They are essentially being punished for trying to protect themselves which the officers are failing to do. Tell me who should actually get the sentence for this.
