Chicago DUI attorney comments on citizens' arrests and social media

This Chicago DUI attorney has posted here and here about Big Brother. 

Here is another use of Facebook being used to "solve crimes.

From the nytimes.com:

This city is famous for its snarled traffic and infamous for its unruly drivers — aggressive rule-breakers who barrel through red lights, ignore crosswalks and veer into bicycle or bus lanes to find open routes.

 Now, the city’s overburdened traffic police officers have enlisted an unexpected weapon in the fight against dangerous driving: Facebook.

The traffic police started a Facebook page two months ago, and almost immediately residents became digital informants, posting photos of their fellow drivers violating traffic laws. As of Sunday more than 17,000 people had become fans of the page and posted almost 3,000 photographs and dozens of videos.

The online rap sheet was impressive. There are photos of people on motorcycles without helmets, cars stopped in crosswalks, drivers on cellphones, drivers in the middle of illegal turns and improperly parked vehicles.

Using the pictures, the Delhi Traffic Police have issued 665 tickets, using the license plate numbers shown in the photos to track vehicle owners, said the city’s joint commissioner of traffic, Satyendra Garg.

Despite some concerns about privacy, and the authenticity of the photos, the public’s response has been overwhelmingly positive, he said.

Is there any doubt that there will be an increase in citizens’ arrests here using the same technology?
