world have security measures, some probably a lot more high tech than what Dubai has. And still forbidden items (razor blades, drugs, etc.) manage to get into the prison population.

This is just the nature of life, especially in prison. If people want something badly enough, they will find a way to get it.

I'm not saying that contraband materials are rampant, or that prison security measures are completely useless and ineffective. But I certainly don't think you can say that a prisoner getting hold of a razor blade while in jail would be "absolutely impossible".
