It is illegal to shoot somebody. If there is anyway you can escape, that is the correct thing to do or you will go to jail. Best thing to do is move to a safe neighbor hood. That being said... I would be happy to hold somebody at gunpoint with any type of firearm until the police arrive.
If it is an unarmed teen.... I may consider having a talk with him. Maybe you could change his life for the better? Maybe not?
And there you have it, a golf club and a stern voice is all you need to defend yourself.
