It's probably my PTSD but my biggest fear is getting raided by SWAT in a "wrong house" mixup or for some other stupid reason. In such an instance I would likely kill one or more of them. I have a family in my house that could be injured by them in the process. I've always wanted a camera system that had remote encrypted storage so I could prove the truth in court.
I just re-read this comment and I'm clearly nuts.
