Thought you were referencing the Lewiston ME mass shooting of October 25 this year.
The thread has information and lessons that are pertinent to anywhere.
Copy that. The places in Lewiston were posted no firearms. Military trained firearms instructor saw easy targets with zero resistance. Someone engaging him might have caused him to break off the attack. We’ll never know. I hope the owners of those businesses remember their actions caused lives of their customers to be lost.
