The very fact that this inmate was able to get as far as he did with his fake bomb suggests that the Broward County Sherriff’s Office doesn’t trust the searches and pat-downs performed on inmates prior to their being incarcerated.
While it is relatively normal to err on the side of caution in such a situation, they should have known better than to buy into this story if they had any faith in their own security system for controlling inmates.
Inmate in cell == I gotta bomb! Let me out or Iz bolws it up!!!
Guard === OK, hang on there, don’t get excited.
Inmate === I mean it!!!
Guard === OK, go ahead, I just needed to move the coffee maker.
