Good. Thank you.
Potentially there are two problems with that. The first is the definition of a crime gun. It has been suggested by earlier witnesses that perhaps if you have a very broad definition of a crime gun to include any gun found at a crime scene, even if the crime wasn't violent, and that's included in the definition of a crime gun, it's probably not all that useful a measure. It might be a true answer, but it's not particularly useful.
Another problem, of course, is that there is inconsistency in the tracing of actual crime guns across the country. It has been suggested that we need to have a national strategy for tracing all crime guns.
