Absolutely. In fact, there's one example I provided in the package to the committee as well. It's about a specific scenario such as the one you indicate. A family believed that the father, who was suicidal, only had 13 guns, but the reality was that he had 21 guns. It was only through the registry that police officers actually found that out. Again, once they found the 21 guns, they continued to search.
