There were 45 shooting attacks at K-12 schools where there were school resource officers or other types of law enforcement officers. Thirty-nine of the cases involve casualties other than the attacker. In those 39 cases, there was on average 1.3 murders and 2.9 injuries.
About 44.8% of public schools have sworn law enforcement officers carrying a firearm and with 99,073 public schools during the 2024-2025 school year, that means about 44,385 of the public schools have sworn law enforcement officers carrying a firearm. By comparison, there are about 13,156 public schools with armed teachers. So there are about 3.37 times more public schools with law enforcement and other armed guards than allow teacher to carry concealed.
