That is not what I said. Please read what I said. I said nothing about attacking a photographer. The person photographed may bring a civil suit against the photographer. Taking a person’s photograph without his/her permission is an invasion of ones privacy.
No its not, maybe posting online it is in some specific cases, and that's the websites problem.
Regardless, that doesn't apply for police on duty. They have no right to that type of privacy. Common sense should tell you why.
