The accompanying message is simple (and cryptic):
Surveillance Rpt #274789: Suspect Aiden Pearce was seen on Lake St. ctOS is pulling video, will be updated tomorrow.
Aiden Pearce, of course, is the “grey area” main character from Watch_Dogs, a man who is not necessarily a goodie or a baddie, instead, a highly-skilled computer hacker obsessed with surveillance and monitoring. The Irish-born American citizen has featured in the game’s trailers to date, where – equipped with his Profiler – he can access, control, and tap into any computer system.
…so the question is: What was he doing on Lake Street?
