Officer went back down the ladder after shooter pointed his rifle at him
Like with Parkland and Uvalde, I don’t entirely blame the officer. Police around the country have repeatedly shown us that they are unwilling to take on a person with an AR-15 while only armed with a 9 MM. The answer is to ban these weapons.
That said all of these officers could have done more. Fire off some shots on your way down the ladder. If nothing else, that stalls the shooter and alerts the agents around Cheeto. They could have tackled him several seconds sooner.
