Haha, I guess the idea isn't as nearly as even as I thought.
For possible context, I should say I am a federal employee who deals with confidential data on a daily basis. Disclosing data or misuse of any kind constitutes SERIOUS repercussions but also the data is inadmissible in court if it pertained to something. For example, if I was working on a survey that polled respondents about their income and I see John Doe wrote $2,000,000, I can't get his IRS records to compare and if there is a discrepancy, use that information in any way to bring suit (or for others to do so). That being said, I really just had in mind a system that could only be used in a court of law when dealing with accidents or in some situation where proof was needed. I didn't intend for the government to note how often you pick your nose or even how often you text. Maybe the internal camera is over the top but I didn't expect to have all the kinks worked out with a simple thought on a Tuesday morning at work.
Many buses and metro systems already have much of this in use. In fact, my wife received a ticket in the mail due to a rooftop camera from a bus. Also, this video became all the rage this past college football season (within the FSU football community) when the starting tight end for the Florida State Seminoles was injured on his motorcycle as caught on camera by this bus.
