In 1993 two men stormed into a bank in Bartlesville, Oklahoma brandishing weapons. They held up the bank, the customers and jumped in their car to leave town (they were from Oklahoma City). They got exactly four blocks when the cops stopped them and opened fire killing one. The other is in jail for the rest of his life for bank robbery and 2nd degree murder because his partner died while he was in the commission of a felony.
As a police officer I was guarding a wiseguy (made man) who was from Newark, New Jersey and was in Oklahoma as a witness to a major fraud case (they transported him there while he was serving time for murder). While waiting to testify, he read the newspaper of what happened and sat there laughing. He looked at me and told me that people who come to rural towns and do stuff like that are obviously ignorant amateurs. When I asked him why, he said because every person in town has a rifle on a rack in the back window of their truck and if you go busting in somewhere shooting the place up, you're going to die in a hail of bullets. He said that if it was so easy then his 'crew' would be running out to Podunk USA all the time to rob banks. But they don't because it's suicide. That's why when someone in their crew does do a major hit on something, it's usually a building like an air terminal or a place in a large city where you can be assured that most people won't have weapons.
Course, I wouldn't expect the left to listen and LEARN anything...
