Mailing without a hidden copy, revealing information addressed by a particular title.

The City Council is admonished as being responsible for an infringement by violation of the principle of confidentiality, for having sent an uncopyed mail to workers in the local police force, identifying them with first and last name and e-mail address, revealing those who had not yet made the training session of prevention for the covid-19, and who as a result were listed on a "morious" people's stock exchange.
