Absolutely. In the United States, with the National Institute of Justice, they're struggling with that question. How do you confirm that this avoided that particular outcome? It ends the confrontation so that the officer isn't getting hurt, the suspect isn't getting hurt.
As Mr. Palmer mentioned, I have travelled the world and heard from law enforcement officers, “Thank you for this technology, because I didn't have to get hurt and I was able to take this person into custody without incident.” Again, that's why this tool is available.
It's not perfect; none of them are. It's a very difficult situation. It's giving them another tool in the tool box.
