Questions the prosecution could ask that cannot be used to save the assailants....

Were you in any danger on your own property?

Did the deceased have a weapon at any time??

Did you leave the safety and security of your property to encounter the deceased??

Summary...
You left safety and security to confront the victim and were armed and outnumbering the deceased off your property. You created a volatile and hostile situation. Guilty.

Ga law does NOT permit citizens arrest where wielding a firearm or use of force. They did both.
Ga law does not allow you to create a volatile situation against another.
Stand your ground is NOT applicable when you run someone down.

Regardless what happened before the confrontation, these two started it all. They lied about reported break-ins the past months, they lied about the jogger breaking in and stealing. They lied about him. They lied about following him.
