http://www.nbc5i.com/news/13717282/deta ... w&psp=news According to a post at www.subguns.com the launcher was a 37mm which are unrestricted. 40mm launchers are NFA and require a tax stamp. They also say that the child porno was actually regular, legal porno. I do know if this is the case. That explains why in the article they say no charges are expected. The moral of the story is be careful who you let into your apartment.
