Intruder: You’ll Have to Kill Me—Homeowner: Challenge Accepted

But even if you think she’s cheating with another man in his house, if she’s there of her own free will, the law says you don’t get to enter the home by going full battering ram on the front door (and then the dude). That’s the line 31-year-old John Fisher crossed late last month in Scott County, Missouri, when he went looking for his wife—and ended up getting shot dead for the trouble.

According to the Scott County Sheriff’s Department, Fisher showed up just before midnight at the front door of Austin Glastetter, furious his wife was inside. Instead of angrily walking away and waiting for her to come home, Fisher strapped on brass knuckles and began pounding on the door in an attempt to bash it in. A justifiably terrified Glastetter warned Fisher several times to leave and told him he was armed.

That didn’t deter Fisher one bit. So, when he smashed through the door’s window and reached inside to unlock the door declaring, “You’ll have to kill me,” Glastetter did exactly that, proving even if his moral character was up for debate, his aim was still true. All four of the shots he fired struck Fisher in his chest. When law enforcement arrived on the scene, they found Fisher lying on the porch dead. Sheriff Derick Wheetley called it “a tragic but clear case of self-defense,” citing Missouri’s Castle Doctrine—a stark reminder that the law takes the sanctity of a man’s home seriously, even if what’s going on inside may be far from holy.

But There Was a Time: In 1859, Congressman Daniel Sickles shot and killed his wife’s lover, U.S. District Attorney Philip Barton Key, son of Francis Scott Key of Star-Spangled Banner fame. And he did it in broad daylight right across the street from the White House. Despite being charged with murder, Sickles was acquitted following only 70 minutes of jury deliberation after claiming “temporary insanity.” It was the first time a “temporary insanity” plea was used successfully in U.S. history.
