Because the word "identified" comes with special significance. It's a positive identification from the police as a matter of fact, and it's an official position. It carries weight and is reportable without the risk of libel. A low-level lieutenant who heard a name and then told the media to curry favor is not identifying. He's providing a lead, which must be confirmed from another source.
Compare: We are positively identifying the suspect as John Doe, who is in custody.
With: Hey, we are looking at John Doe as the suspect.
One is identification, the other isn't. It's a legally-important word and distinction. Again, I worked in the field, and your shot at the end about my personal bias was uncalled for and marred your otherwise good parry.
