This the survey you were referencing? Depending on how someone may wish to define active peace officers (full-time, part-time, auxiliary, reserve, etc), the numbers a couple years ago seem to be tallied anywhere from a high 600K to more than 800K. Also, participation of local and state LE agencies with federal agencies, like the Census Bureau and the FBI, on matters like this seems to vary a bit. Other "sources" acknowledge their numbers are "general estimates" derived from a myriad of other sources. The (albeit) older stats I saw indicated that close to only 3% of all active peace officers would ever fire their weapons outside of a range during their career, but that was in the early 2000's. Also, one of the gun industry stats I heard in an armorer class was that close to 65% of LE agencies in the US had 10 or fewer full-time sworn members, but they were unable to given a definitive source for those numbers. Now, as a LE firearms instructor who decided to take a sabbatical 3 years ago, I've not kept up with these kind of stats quite so much. My interests are more in the skills-oriented aspects, policies & procedures, equipment maintenance, changing laws and how firearms trainers can be developed to better teach adults. That said, having followed some of the reported OIS incidents being reported in the general news, and listening to trainers discussing current incidents, and following some LE-oriented training sources, I'd not be surprised if some of the newer, younger cops (10 years or less on the job) might be showing a tendency to "go to guns" more quickly than the cops of my generation. I've occasionally discussed this concern with current trainers and older, or recently retired, folks from other agencies, and I've heard some similar suspicions voiced. Evolving and carefully crafted training issues, especially regarding policies involving use-of-force (and especially deadly force), and keeping up with relevant legal updates (changing laws) are critical. When I was a young cop, the joke usually heard was that a modern shooting policy could be as simple as "reload as necessary", but then we started seeing new court cases (Tennessee v. Garner was a big one, obviously) and changes. The High Liability section (think color coded pages) regarding Deadly Force in many modern Policy manuals became longer and clearly detailed. Discussing and reviewing (reminding staff of) existing policies and legal updates is pretty damned critical.
