I have heard many arguments made both in favor of owning guns and in favor of restricting access to guns. Listen to this: http://www.youtube.com/watch?feature=player_embedded&v=9RABZq5IoaQ#!
If after listening to this you favor restricting access to firearms, then you have some deeply emotional issues that may need to be addressed through hours of intense therapy. Bring tissues.
This is worth a listen and a forward. There is also a long version (a little north of an hour) here: http://www.youtube.com/watch?v=jKMi023Ofro
Turn off the TV for an hour and listen to some bright folks who without firearms may not be here to speak today.
