Welcome to the new Mont Order associate J.M. Porup. Below is an excerpt of a solid article regarding technology and law:
What Technology Dictates, the Law Transcribes
His focus seems to be: What policy / law / rule set should govern the use of police body cameras?
This is, IMHO, the wrong question to ask. When law and technology collide, law always loses. Even a brief glance at history shows that might makes right, and law picks up the pieces afterward.
Or to be more precise: Technology redistributes social and political power, and law codifies that new power balance.
