PITTSBURG COUNTY, Okla. (KFOR) – An Oklahoma mom’s Tik Tok video preparing her son in case of an armed school intruder and how to use his bulletproof insert backpack has gone viral.

When I bought it in June, I paid $34.99, but the backpack goes on sale regularly. As of Monday, the cream-colored bag was on sale for $26.99, and there are plenty of colors to choose from.
