Many people have criticized the police for this incident, such as "everyone has seen it. What good is arresting a person or two" or unfair prioritization just because the victims are celebrities. About the first criticism, I have to criticize the criticizer. If spreading the photos in public is illegal, spreading them privately is legal, then the police were merely doing their job. They can go only as far as where the evidence is. The second criticism is understandable, but it's not excusable at the end of the day.
The following is that I have to criticize against the police. They've arrested some John Doe here and there. If spreading these photos publicly is illegal, then the first suspect that should be arrested is the newspaper or magazine that publishes the photos! So what if the important parts are censored, cropped, or covered by text? Selective prioritization is minor; Selective arrestment is no better than a bully!
