Ireland's human rights watchdog is calling for the government to scrap plans for Gardaí to use body-cams.
The cabinet signed off on the proposals in June, saying they would help to police protests and other events.
But in a submission to the Department of Justice, the Irish Council for Civil Liberties claims they would breach privacy and trust.
The ICCL's Doireann Ansbro believes the negatives of body-cams outweigh the positives:
"The roll-out of body-worn cameras constitutes an evasive and unnecessary breach of our privacy rights. They constitute close range filming. They'll gather not just video but audio as well."
She went on to say they are "not convinced that the clear breach of our privacy rights is justified by any reason that the government has given so far."
The technology is already in use by police forces in a number of countries.
