Since then there has been several mass casualty shootings in the states.
Wish I burned them now.
edit:
I didn't get rid of my collection over any huge reason, just didn't want the liability sitting around home when I haven't gone shooting in years. That said I feel like I've made a critical mistake in yielding my arms to people who would likely be less responsible than I during my ownership.
For anyone in the same position remember you can disable most firearms pretty easily by kludging a part or two. Hopefully will save someone that nagging feeling I have.
