For the OP, not saying you're being dishonest but this sounds like there's more to the story. Are you related to who owns the property or is it a family friend? You said your FIL has not paid a trespass or access fee. Has your husband? I agree your FIL sharing your pictures and erasing your cards is just plain wrong. It's kind of surprising that he would trespass on somebody else's land to do so and risk being arrested. From your description, it sounds like only you and your husband knew where you placed your game cams. If so, it would be mighty hard for your FIL to find your cams and know they were your cams and not somebody else's. You definitely have some things to talk over with your husband but it sounds like there's just more to this story. It's none of my or anybody else's business but if you're asking for an opinion, it's hard to give a good one without knowing the whole story.
