Regarding the Binghamton shooting:
One receptionist was killed, while the other, shot in the abdomen, pretended to be dead and then crawled under a desk and called 911, he said.
Police said they arrived within two minutes.
And what did the police do when they arrived?
Police heard no gunfire after they arrived but waited for about an hour before entering the building to make sure it was safe for officers. They then spent two hours searching the building.
Read it here.
While the police waited to "make sure it was safe" to enter the building eleven more people were killed inside. And when they did enter, it took them two full hours to search the building and find the twenty-six people cowering in the basement.
