Until recently cameras were toys of the rich. Along with many other industries like wrist watches, cell phones changed camera industry also.
Recently India was awash with scams. People were in the street protesting against corruption.
I realized that everyone has a phone – and a camera. Why can’t such a formidable presence of evidence-catching machines be turned against the corrupt?
Finally a corrupt person is going to spend all that cash somewhere. Why can’t the mass turn into paparazzi and catch every possible movement of someone on the black list?
Later, the pictures may be circulated by some means – from MMS to Facebook or Tumblr. Such images can be used to estimate the person’s (or his familiy’s) spending habits and can be questioned for consumption disproportionate to the income.
