That searchable database is frightening. The anti-gunners are rabid about the "legitimate" need for firearms ownership, but really, what legitimate need is there to post this information? I can see absolutely NO good coming out of it.
The argument that people have a right to know if their kids are going to a house with a gun is nonsense. First; only a small fraction of gun-owners have licenses. Second; its not the people with LICENSES that you need to be afraid of. Third; a parent who doesn't know the host parents is NEGLIGENT!!! At the very least, go and meet them to see if they are someone that you trust with the life of your child.
