That happened in New Zealand a few years ago. The police missed their target (an actual active shooter running on foot) and instead killed the driver of a nearby van. I don't know how you can be trained to use a gun and not learn about looking at what you're shooting it at.

Handguns are difficult to use. Moving targets are hard to hit. Extensive training helps, but many people who have found them in situations where they need to use that training have found their performance suffers.
