Guilty or no, I wouldnt want to have cameras/recording devices hidden in my house, either!
Me either. I have never had my home be the subject of an intense search by LE...but I can only imagine that feels like to know people were trampling all through your house. Looking everywhere and taking what they want. It would feel like a form of violation I would think. And especially if you feel there is a potential that LE may be trying to mount charges against you.
I can understand not wanting cameras and bugs in their house. I am not saying they don't deserve to have their house searched - or cameras placed in them - heck I would love to be able to hear what goes on in that house! But I am just saying I can understand their side too.
