Guns

I decided to go watch some movie shootout scenes that I have always liked in that way you like a scene from a movie, or think a scene is powerful or provocative. I also like the final battle scene from Lord of the Rings: The Two Towers. But this current exercise was about watching fights, battles, conducted with guns, specifically, and in light of last week's school shooting in Florida and all the school shootings that have come before it. What would I think of these shootout scenes in the shadow of another gunning down of kids at school by another kid?

An observation from watching the clips - 

Both sides have them. The guns. The value of guns in these scenes don't distinguish between good and evil.

I am not currently in possession of some big opinion about guns or gun regulation. I'm just asking myself why I've like these movie scenes, these gun fights, these bloodbaths?
