There's 183,000+ K-12 schools in America that have served hundreds of millions of people with 60 million current students, there's been around 400 schools that have had a shooting since 1970 with around 300 deaths........in 50 years. Also not all school shootings have been random, a good number of them over the years have had targets, such as gang violence. Do the math.
They're putting out propaganda all over the internet and television that kids across the country are scared to go to school and every kid will be affected by gun violence. Shit is stupid as fuck and they're trying to make people scared for the sake of pushing an agenda. A kid has a better chance of winning the lottery than being shot in their school.
