intelligence center david greene senior staff attorney at the electronic frontier foundation and jennifer granick civil liberties director at the stanford center for internet and society. well, let me begin with you, jennifer. we heard that sheriff's deputy from los angeles saying we're already being on-camera everywhere with atms and red-light cameras, fastrak. so what's the big deal? how is this different? granick: what's different is whether all that information is aggregated and one party -- in this case, the government -- can get ahold of all of that because it means that they know so much about us that was really something that was never recorded before or even was just recorded for specific purposes, and now it can be used for more general policing, or it could be abused. shafer: but for general policing isn't that a good thing? don't we want to be safe? granick: there's an assumption that if there's less privacy, there's automatically this uptick in security and that people want that. i don't think we can just assume that we're trading privacy for security every time and people like it. i
