While crime rates overall have been steadily falling over the years within the US, cases of mass shooting incidents are a strong outlier. According to an extensive research performed by Harvard University, the rate of mass shooting in the US has more than tripled since 2011. Between the years 1982 and 2011, a mass shooting incident occurred about once every 200 days. However, between 2011 and 2014, the rate was one mass shooting occurring every 64 days. Since then, it has gotten even worse.
