Melissa Joan Hart Instagram – It has been 25 years since the tragedy at Columbine High School, and not much has changed. Please read the following repost from @giffords_org ・・・ 25 years ago today, 12 students and one teacher were shot and killed at Columbine High School in Littleton, Colorado. Another 21 people were wounded in the shooting. For the generation of young people who have grown up since, gun violence is still their reality. It’s beyond time we change that. As we remember the lives lost and those forever changed at Columbine, we recommit to making our communities safer for this generation and the next.
