When you confronted these people, what is it that gave you an indication or an impression that they were there to disturb the peace in your area?  The reason why I'm putting this question to you is because you are saying that subsequent to their questioning, it emerged that they were there to disturb the peace in your area, from the responses they gave to those who were questioning them.  Now apart from what emanated from the enquiry you conducted at the hills, what indication, or what conduct of these people gave you an impression that they were there to disturb the peace in your area?
