Thank you, Mr. Chair. I'd also like to thank the two witnesses for sharing their expertise, especially on the security information. I would like to ask one of them a question.
We've talked a lot about systems that have been put in place in recent years, including sniffer dogs and other systems to detect the drugs that might be found in prisons. Some witnesses have said that there are fewer drugs in our prisons. Others have some doubt about the effectiveness of these systems.
Could you please talk about the effectiveness of these detection systems? Should more resources be dedicated to them?
