The older & newer SOP reports can make for interesting reading (probably especially to non-LE folks who haven't come across much similar info), as can the FBI's annual reports on LE feloniously killed.
Then, there's the info collated and presented in the FBI sponsored LEOKA class (Law Enforcement Officers Killed and Assaulted), but that's LE-Only for attendance.
There are always going to be disclaimers and warnings against taking the statistics too literally, of course, or out of context, and rightfully so.
While it's harder to find, working LE (and retired-but-active members of some training organizations) can also find seminars & conferences where cops who have been involved in shootings are presented as guest speakers. Interestingly enough, in the last conference I attended where some cops were speakers, all of them included how important it had been for them to either start out using aimed fire, or switch to making aimed fire, in order to stop their attackers during their encounters. All of them had been themselves seriously injured during the shootings, too.
Lasers? Still more of a private gun owner market, it seems. You can find large agencies prohibit lasers for even off-duty weapons.
On the other hand, however, you can also find (where permitted) aging/retired guys who have discovered the merits of lasers for aging eyes that can't see diminutive sights with tri-focals as distance increases from close range threat targets.
Having spent some years watching occasional shooters bring laser-equipped handguns through various ranges, it's not uncommon to see the significant number of laser users take longer to shoot their identified threat targets ... but that's probably a training issue for many folks.
