He would use the same memory card and high end camera both during "stakeouts" for surveillance photos as well as listing photos for the homes he was selling.
One day he uploaded the entire contents of the memory card to the MLS on one of his public listings, surveillance photos and all. I'm pretty sure everything was up for a few days before being cleaned up.
It's been years but I still haven't made up my mind on whether that makes him a worse agent of law enforcement or real estate.
