Like I said, things differ in different locales. And the number of people who are involved in law enforcement here are only a minute number compared to all the people in the U.S. who are employed as sworn personnel either as their profession or in a reserve capacity. I don't think you can apply what you see here as an average representation of the law enforcement community as a whole. And many officers only rely on their issued flashlight (usually full sized or as equipment in the car), they don't even carry a personal light on their belt. There are also other considerations to take into account, like whether they work days or nights.
Maybe if you take a look at what you see locally; it will give you a better idea of the variety. Not to say that the PM6 is not a viable light, it's a great value compared to the others, but Pelican is still emerging from their mail-order roots as a company, and the majority of their public safety sales are to fire departments rather than police. Pelican's primary focus with lights seems to be for diving and firefighting.
