Realistically though, for that to work the US needs a sweeping reform of drug and gun laws. Right now, if I'm a drug mule with a ton of meth in my trunk and get stopped on some lonely road, I have the choice between shooting the cop and maybe get away or getting a life in jail for the drugs.
Here in Germany, you usually get out after 5, 6 years as a simple mule, and our cops (unless you're on an international route where cops can claim Schengen border duty rights) can't simply demand to open your trunk unless they have reasonable suspicion - and it's really hard to get your hand on a gun. As a result, our cops don't have to be afraid for their life at a random traffic stop.
There's a reason why cops are so trigger happy in the US, and it goes way beyond shoddy training.
The scenarios presented were laughable, badly-acted and completely unrealistic. Worse, every single one ended, by default, with the suspect pulling out a gun and shooting at the user. All of them. This is, of course, completely counter to reality.
One could say that the issue is then the quality of these systems, but the fact that, apparently, it has been a viable business for going on a decade shows me that the issue isn't being taken seriously be their customers - that is, police departments and their trainers. The issue is, in fact, the institution as a whole. They're fundamentally incapable of reforming themselves.
