To tag robbers and link them back to the scene of the crime. From the article, 'The mist — visible only under ultraviolet light — carries DNA markers particular to the location, enabling the police to match the burglar with the place burgled. Now, a sign on the front door of the McDonald's prominently warns potential thieves of the spray's presence: "You Steal, You're Marked."' Developed in Britain, it's yet to nab a criminal but it will be interesting to see whether or not synthesized DNA will hold up as sufficient evidence in an actual court of law." So it's not just for copper thieves.
