It’s a bad idea to put nude photos on a phone, but these cops were sending even bikini shots. That’s not the issue. Police have zero moral or constitutional right to search a phone unless they #1 believe it contains evidence directly related to the crime and #2 they have a search warrant.
Some might say the women voluntarily gave their passwords. Regardless, police are acting on behalf of the state. They are authority figures with the full power of the state backing them. There is no such thing as voluntary consent in situations like this, especially when the women are drunk or otherwise incapacitated. The burden of complying with moral, constitutional protections must fall ENTIRELY on the government.
Regardless of the matter of a password, there is no reasonable explanation whatsoever for the cop to mail out anything from her phone, even if it could be considered “evidence”, which it certainly was not in this case.
