There are a few things. First of all, the amount of ammunition available to illegal gun users is extraordinary, so each of those shell casings represents a projectile that flew in our city. That does not account for the use of revolvers, which don't produce shell casings at the crime scene. The amount of ammunition available is definitely an issue.
You mentioned overcapacity magazines. Our analysis shows that our seizure rate of overcapacity magazines has risen threefold, so there's definitely an issue on the availability of the prohibited devices. We have recovered handguns that were modified for automatic fire with some internal manipulation, which is a growing concern, because we're seeing those being seized as well.
