Security cameras are definitely on the list of things to get at tax return time... can't afford them right now. Now you've got me curious...what was the research? You don't have to answer if it makes you uncomfortable...
I was looking for advice on what to do and some places say just ignore them, they lose their power if they don't get a reaction. Other's say whip out the camera when you see gangstalkers, they hate being recorded. For my own peace of mind, I've been ingnoring. The other option would be to go sit on the front stoop right now and pretend to be looking at my phone and wait for someone to come by and take a snapshot as they drive by, but that would have my husband worried again haha. Also if they know what I'm up to they won't drive by anyway...
