Columbine was over 25 yrs ago and nothing has changed. Hundreds of our most vulnerable murdered, nothing happens and we go on until the next and the next and... We think we have freedom, have elected officials that will save our loved ones. They don't want to stop the $ and that is what it would mean. Australia had a mass shooting and they stopped it from happening again. New Zealand had a mass shooting and they stopped it from happening again. America won't stop it...greed.
