Sure, but surely sketches can be just as twisted and misused (e.g. drawing a defendant with a menacing snarl), and even more so given that there's no source of real truth.
Kind of related, in Sweden, there's been a murder case in the newspapers the last months where the defendants' heads were blurred in photos during the trial and their names were anonymized. As soon as they were convicted, full photos and names were published. Here the idea is to protect their identities until found guilty. I don't know if this is regulated by law or if it's just a matter of press ethics.
