I believe the research we're doing today is the best available. We are following the ethics standards set by our leading institutions worldwide, not just in the United States.
I can tell you that in the classes where law enforcement officers do get trained, we don't de-select anyone. In fact, we looked at recent studies where the members in the class had a previous heart attack or a previous heart condition, or had been exposed to that. We've also now been subjecting them to alcohol, or that type of application—which is also going to be seen on the street—and we are also exercising them to the point of their becoming acidosic, literally exhausting them, before hitting them with the taser, and then scientifically measuring their blood, breathing, and pulse rates. We're using an ultrasonic waveform so that we can see how they're reacting. That's being done independently of our company. It's being funded by the National Institute of Justice, the University of California at San Diego, Dr. Ted Chan.
So I do believe the research is out there today. While you'll never be able to look at every possible scenario that exists, the research certainly covers the vast majority of cases that exist within the human body.
