Prison problems

Problem.

Answer.
Stop visitors. Totally.

Problem.
Radicalisation of Muslims. (How is it possible that one can own to being Muslim and committing a crime?)
Answer. Stop freedom to associate. Imprisonment should mean just that- in a cell. This would also reduce to zero, violence against prison officers.

Problem.

Answer. They should have thought of that before they committed a crime against society. Suspend all Human Rights.
