Not exactly confidence-inspiring, is it?

They looked at hit rates in two ways, “incident level” and “bullet level”. On an “incident level” basis, they found that officers got at least one hit, regardless of the number of rounds fired, in about 54% of the shootings, just barely over half of the time.

However, on a “bullet level” basis, they found that out of 354 shots fired, there was only a 35% hit rate. One half of all officers missed with every shot they fired, including one officer who fired 23 misses and no hits. This means that six out of every ten shots fired was a miss. How does this happen?

Let’s look at this “amount-and quality- of firearms training” in Dallas, which is actually a very representative sample. Officers qualify with their firearms once per year. That’s right, once. The course of fire they “qualify” on is a joke, essentially a sobriety test for anyone with any skill at all with a gun. I, or any other competent private sector trainer, could take a brand new shooter, with no prior training or experience, and have them pass this course of fire at the end of one day of range training. DPD officers receive “firearms training” once every two years, consisting of 50-100 rounds of firing in exercises and scenarios. That’s it.
