I read this article from Yahoo about facial recognition software being used by FBI through North Carolina Project. For others who see this a threat, may find this software an intrusion to privacy. But for others who have done nothing wrong, should not be at all alarmed.
Criminals in different ways of apprehending them should be behind bars if proven guilty. One criminal was caught through the software in spite of the change in identity. I guess even if the software may bring dozens of people with similar resemblance, this can somehow aid the police department in filtering who should be sought.
I only wish this can be done elsewhere too. Perhaps, unsolved and unjustified crimes can be decreased.
