So last night about 930ish I'm outside spraying wasp nests in my backyard when I see my neighbors that live in a known drug house perusing the fence next to my yard. Their house is caddy corner to mine so they were in another neighbors yard. As soon as I got to the corner that they were in, it was two girls seemingly acting as lookouts for a guy that came walking around my front yard, I looked up and said "Hey I didn't see you there, you startled me" and one of them said "I'm out here looking for my ID" just as she said that loudly a guy came walking through my front yard into the back yard of another neighbors then into their yard not making eye contact or saying a thing. I thought that was odd as why would someone be out in a yard looking for an ID when they shouldn't have been in the neighbors yard in the first place. Well I played dumb to see if I could catch on to what they were doing. I come out about an hour later to "tinker" with my ac condensor outside and they're still there. They told me one of them is on probation and they both just got back in town. Said their house was robbed while they were gone and wanted to know if I had seen anything in particular. I said "no" and they said their house has been hit 4 times and one down the road has been hit twice so the people moved out. I am cleaning out that corner of my yard asap, installing motion sensor flood lights over there, and have my 80lb dog on free roam inside the house now in case they decide to visit while I'm not home. I have also called the cops and they put my house on house watch, and I will be alerting both neighbors next to me of what is going on also. Is there any other tips, ideas, suggestions? And yes I am working on getting a firearm and plan to exercise the castle doctrine if need be.
