In the US at least, no release form is required of those pictured in a news article.
If you are in public and the photo is “newsworthy” your image can be printed in a newspaper without your consent.
“Use of someone's name or likeness for news reporting and other expressive purposes is not exploitative, so long as there is a reasonable relationship between the use of the plaintiff's identity and a matter of legitimate public interest.” - http://www.dmlp.org/legal-guide/using-name-or-likeness-anoth...
