On November 2, 2021, a teenager was shot and killed in Corpus Christi, TX, following a school lockdown after he reportedly brought a gun to school. Aransas Pass High School went into lockdown mode, and a middle and elementary school went on lockout, meaning that no one could enter from the outside. Fortunately, no other children were injured.

In October 2021, police responded to an Arlington, TX, high school shooting that left four people injured. One student underwent surgery and was placed in intensive care. All four victims survived. The shooter was an 18-year-old student at Timberview High School.

Throughout the country, in 2021, there were at least 144 incidents of school gunfire, leading to 28 deaths and 86 injuries. A shooting on November 30 at an Oxford High School in Michigan left seven people injured and four people dead. The shooter was a 15-year-old sophomore who fired at students using a semi-automatic handgun.

These shootings, of course, aren’t just happening in schools. Overall, in 2020, more than 600 mass shootings, defined as situations where four or more people were injured or killed, occurred in 2020.  

Because of these and other tragic events, schools and businesses around the country are taking action to help mitigate gun violence. One of these actions includes installing a gunshot detection system.
