I absolutely agree that the safety of staff is paramount and important.
We work on an evidence base. We've looked at the needle-syringe programs that have existed since 1992. It's been almost 20 years that they've existed around the world, and as I mentioned, in multiple sites and in different contexts. There has not been a single case in which they have been used as a weapon.
There's one example I'd like to point out. In Germany the staff were also very much against it. They were concerned, and it's an understandable concern: needles can be used as weapons. But in that case they had the program implemented and the staff became wholly supportive of it, because they felt they were protected in the end. There's less chance for accidental needle injuries when the equipment is in a specific place in each person's cell. They know that when they search someone they're not going to be pricked. And if it does happen, God forbid, then it's not with a needle that has been passed around by numerous people and possibly infected with HIV or hepatitis C.
