At the Brazil school shooting:
“Police were alerted to the shooting when two young boys, at least one with a gunshot wound, ran up to two officers on patrol about two blocks away. The officers sprinted to the school and at least one quickly located the gunman on the second floor and traded shots with him.”
Whereas at Columbine, police and SWAT refused to enter the building for almost two hours. This, despite being aware that a teacher was bleeding to death inside the building. The killers were dead for an hour before anyone ever attempted to enter the building.
