People...and sadly, too many kids...are dying simply because some gun owners want the "Pleasure" of shooting Assault Weapons...this is not a rational tradeoff...bans on certain weapons, plus restrictions on ownership are sensible measures that have been shown to save lives...so enjoy your many other weapons that don't kill others so efficiently...it won't kill you to do without a few extra thrills.
To not take such actions is incredibly selfish and insensitive to all the current and future victims as well as their grieving families.
