This raises a particular issue, and I want to be clear on the point. We're talking about ion scans in the context of visitors, but let's not forget that ion scans are used in the institution for other purposes as well. As I said, when we're searching cells and what have you, particularly when we're talking about the opioid crisis that's upon us right now, when there are unknown substances found in a cell, it's important for us and for the safety of our staff to find out what the substance is as quickly as possible. The ion scans provide the only tool we're aware of right now that allows us to do that rapid analysis to at least presumptively understand whether or not we're dealing with something like a fentanyl. As a result of that, our staff take different measures to protect themselves when they're handling these substances.
I just want to make sure it's on the record that it's not just in terms of visitors when we're talking about ion scans.
