So involuntary muscle contractions don't equate to training issues? I think we're right back to "keep your finger off the trigger until you're ready to make the gun go BANG" again.
Except that the work of Heim et al. shows that even highly trained experts' fingers unintentionally stray onto the trigger at an un-nervingly high rate; eg, 60% of German police special forces officers (SWAT team members?) touched their triggers when they shouldn't have. In comparison, 92% of police recruits touched their triggers; thus, training helps, and while essential it is far from perfect.
An involuntary muscle contraction of the trigger finger outside the trigger guard is called "an involuntary muscle contraction". Inside the trigger guard it is called "an accidental discharge" created by the operator.
It's an act of negligence, but pretending that all that is needed to prevent it is training, when studies have shown this to be false, is an act of negligence by the designer and manufacturer of the weapon and by the purchaser and user of the weapon.
I'd also suggest that if police departments are concerned about something they can't train out of their staff (including things their muscle do involuntarily), maybe the answer is to go back to pistols with long, double action trigger pulls. Trust me, if my Beretta PX4 Compact that I carry with a round chambered and hammer down ever fires, it's because someone intentionally applied approx. 6-9 pounds of force on the trigger for approx. 3/4" worth of trigger travel. Certainly nothing unintentional about that.
A long and heavy DA trigger is a proven way to decrease NDs, as evidenced by reports of increased rates following departmental switches to safetiless designs (I'm regarding the long and heavy DA or DAO trigger as an external safety). The shooting improvements mentioned in the OP's article is at least partly due to the improved modular grip of the M&P. If it is true that the department's Berettas were DAO, the lighter and shorter trigger pull would help a lot, too. The department could have bought a DA/SA pistol with modular grips or bought M&Ps with thumb safeties.
