New airport security measures to be announced Friday

(CNN) – All flights entering the United States will be subjected to a new level of security screening, officials plan to announce Friday.

The new security measures, that will be announced by Department of Homeland Security Secretary Janet Napolitano, will use "real-time, threat-based intelligence," according to the official.

The new measures will supersede the measures put in place immediately after the attempted terror attack on Christmas Day 2009, the official said.

"These new, enhanced measures are part of a dynamic, threat-based aviation security system covering all passengers traveling by air to the United States," the official said. "To more effectively mitigate evolving terrorist threats, these measures utilize multiple, random layers of security, both seen and unseen and are tailored to intelligence about potential threats."

Do mean girls turn into mean women?

(CNN) – A principal is under fire as parents demand to know why something wasn't done sooner to save Phoebe Prince, a 15-year-old girl who prosecutors say was bullied to death by fellow students at her Massachusetts high school.

Our Alina Cho tracks down the principal and asks the tough questions this morning.

The movie "Mean Girls" explored the cliques and conflicts that come with high school. As we've seen in too many real-life cases, most recently in western Massachusetts, teen bullying can have tragic results. And it often involves girls hurting other girls.

Erika Holiday and Joan Rosenberg wrote the book "Mean Girls, Meaner Women." They'll join us this morning from Los Angeles to discuss teen bullying and the Phoebe Prince case.

Sound off: We want to hear from you about the bullying story. This morning we're asking do mean girls turn into mean women? What do you think? Add your comments to the LIVE blog below and we'll read some of them on the show.

Teens indicted in alleged bullying death

(CNN) – Nine Massachusetts teenagers have been charged with involvement in a months-long campaign of bullying that led to the suicide in January of a 15-year-old girl, a prosecutor said Monday.

Phoebe Prince's body was found hanging in the stairway leading to her family's second-floor apartment in South Hadley, Northwestern District Attorney Elizabeth D. Scheibel told reporters in the western Massachusetts town of Northampton.

"It appears that Phoebe's death on January 14 followed a torturous day for her when she was subjected to verbal harassment and physical abuse," she said.

Earlier in the day, Prince had been harassed as she studied in the library at South Hadley High School, apparently in the presence of a faculty member and several students, none of whom reported it until after the death, Scheibel said. FULL STORY
