Seriously, what kind of a company will design "Tombstone Cam" for surveillance in cemetery ? To catch a pervert or predator or human-eater? This is bizarre.
Funerals of 'bad guys' are a good way to learn about who is affiliated and has connections, and probably to also pick up on juicy gossip of one form or another
There have been instances of religious/ethnic motivated vandalism before. I'd guess this is the target market.
