Well, duh.
But, Mr. Sheriff, don't you know that by doing this you will increasing the danger for your own staff?
Research shows that physical activity is a great way to alleviate stress and in jail, it also is a nice break from the monotony of incarceration.
Assaults on staff will probably go up as a result of this move.
Congrats!
Bottom line: This is pure politics. The sheriff did not like how it looked when people drive by and see inmates playing basketball.
By the way, there is an online game called "Prison Basketball." So they can still play if they have access to the Internet.
