Yeah, we had one like that out here. A couple surrounded their property with a 12 foot razor wire topped chain link fence, motion detection devices everywhere, searchlights, guns - the whole 9 yards.
Pictures were in the papers because the neighbors were pretty annoyed. Besides the chain link, towers and razor wire not fitting in with the neighborhood landscaping the sirens, searchlights and loudspeaker warnings would be going off in the night every time a raccoon messed with their fence.
About a year and a half later I read that they'd both died, probably from terminal paranoia.
