Photography is a Crime Stopper/Solver, not a Crime.

After the requests have been flowing out from the FBI for imaging from the Boston Marathon Massacre, it's time for all law enforcement, especially those in California, to relax and chill when cameras are pointed at them.  As long as the photographer is not close enough to interfere with an arrest or sidewalk investigation, there is no good reason to attempt to intimidate the camera people with not so veiled threats of arrest, as long as all are in public spaces. Photography in public is legal.  Using resulting photographs for advertising is a civil matter.  Using resulting photographs for editorial or news use is perfectly legal, and yes, Virginia, the photographer may make some money from the deal.

Should a terrorist attack occur, all those cameras are obviously great tools for getting leads on the perps.
