But for the approved ones, those should require a warrant of some sort or other reasonable judicial approval.

If that becomes searchable, then by default they have a registry

Which is the FUCKING POINT.

Having the government snooping into your life when you've done nothing wrong isn't right

Knowing which guns you purchase isn't snooping into your life; it's protecting the lives of EVERYONE around you. Because bullets don't respect private boundaries, you know. Perhaps everyone in school knew his family had guns, but because there's no registry, the government couldn't do shit about it.

How is it that people get more attached to their god damn KILLING MACHINES more than the lives of innocent people?
