Data from surveillance camera can and should be used to hunt down wrong doers in society. But, given how powerful our desktop computers (traditional PC-s, laptops, etc) already are, and how powerful tablets and their app software are getting, there's a huge privacy and safety concern here.

As a simple example, someone with bad intentions and with access to the surveillance camera feed/stream could manipulate a few frames or pictures to make an innocent man a suspect.

So, I guess it would be ok to have wide spread surveillance devices (cameras, or what have you) installed all over the cities provided data from those surveillance devices is made publicly available - IMMEDIATELY ON COLLECTION - to all the citizens and not just held by a few corporations (govt or private).

Let's open up the world. :D
