The company hired to provide security in Metro's Westlake Station  has changed its policy to allow guards to do more than observe and report when there's trouble in the tunnel.

ST:

The change is in response to last month's beating inside the tunnel of a 15-year-old girl by another girl, which was captured on video and made national headlines.

During the fight, three Olympic guards stood by watching, but did not intervene as the victim was kicked six times in the head.

Mark Vinson, president of Olympic Security, said Monday that employees last week received three hours of training in verbally defusing arguments, but it's not yet determined how much self-defense training they'll get.
