if I hear foot steps in the leaves in my yard, okay, I'll do something about it.
When you talk about your rifle near by and you "doing something about it", that concerns me. Hope you meant calling police.
As Spacecoast said: What does this have to do with firearms?
OK, I see were Pax pointed out that it falls under tactics. Call the police or keep an eye on him until he moves on. Going out to confront him wouldn't be the best tactic. Armed or unarmed.
Just my thoughts ont he matter.
