They do things differently in Florida.
John Palmore and his wife Khadeja are separated and going through a divorce. Khadeja reportedly goes to John's house to remove some items. John finds her there, an argument ensues and Khadeja allegedly punches him on the nose. John allegedly then shoots her with his taser gun, to prevent her from getting a kitchen knife. Khadeja says that she threw a flashlight at him to stop him from approaching her with the taser. The Sheriff's Office, it seems, accept John's story and charge Khadeja with battery. John is not arrested.
Somehow, I can't see this scenario happening over here, but who knows?
My thanks to the Florida Divorce Law Blog for the heads-up on this story.
