No offence, but do you really think that giving the ability to to mass scans like this to police officers won't be abused? What's our track record on actually punishing police officers that can have provably (and demonstrably) abused their powers?

I'd almost trust the military more with that technology than local police departments and/or the FBI.

Edit: Also, what are the chances that this technology will spend a lot of time in the field at local police departments before there are any meaningful rules/regulations on how they can use it? During that period no one will get punished for "abuses" because without rules and regulations any use is valid.
