BROKEN ARROW, Okla. (KTUL) — One person is in custody after three suspects in a Wagoner County home invasion were shot to death Monday afternoon by one of the residents.

According to the Wagoner County Sheriff’s Office, the suspects’ getaway driver has been arrested. The 21-year-old woman turned herself in at the Broken Arrow Police Department hours after the shooting, saying she had information.

Investigators haven’t released the names of anyone involved but say the deceased suspects are between 16 and 18 years old. Two of the suspects were armed, according to investigators. One with a knife and the other with brass knuckles.

Mahoney says the suspects broke in through a glass door in the back of the house. After entering the residence, the suspects encountered the homeowner’s 23-year-old son who also lives there.

“There was a short exchange of words and then gunfire happened,” he said.

Two suspects died in the kitchen and a third ran from the home but collapsed and died in the driveway.

Both residents are cooperating with investigators. The homeowner’s son volunteered to go to the sheriff’s office to give a statement.

“Preliminary investigation, it looks like it was self-defense,” said Mahoney.

This is impossible.  We all know that no one needs that awful high capacity magazine, and no one needs an AR-15 for self defense, even against multiple intruders.  And we all know that it’s more dangerous for the homeowner to have a gun than it is for the assailants.  Guns take on a life of their own and turn and shoot the innocent like they have an evil brain.  The report must be mistaken.

No, I’m pretty sure it says what it says, and he is alive and well, and the assailants are not.  He did one thing right, and one thing very wrong.

First, what he did right.  He assumed that if he had not used his weapon, the assailants would have harmed him.  If an intruder is in your home, you must assume they are armed, and armed with more than you can see in the instant you are making your decisions of life and death.  And you must also assume that they are capable of using their hands to kill you.  Finally, you must assume that if they are in your home, they intend you harm.  It may not be correct at the time, but you simply don’t know that and cannot discern their intentions with certainty.

Now to what he did wrong.  He talked to the police.  Boys and girls, don’t ever talk to the police.  Not even if you shot in self defense, not even if you have nothing to hide, and not even if you’re an honest and decent human.  Don’t talk to the police.

Ever.
