Former D.C. police chief Cathy Lanier focuses "on it all" as NFL's head of security

In the high-stakes arena of the National Football League, Cathy Lanier, former D.C. police chief, is leading the charge off the field as the NFL's head of security. Now in her eighth season with the NFL, Lanier is focused on safeguarding the league's venues, fans, players and overall image with a practiced eye that leaves no room for distractions — not even the games themselves.

"I focus on it all. Nothing is more important than anything else," she told CBS News. 

At FedEx Field in Landover, Maryland, Lanier's work was on display recently as she directed staff on moving fans through new weapon-detecting sensors before a Washington Commanders game. She said the stadium becomes a city of 70,000 or 80,000 people for a few hours at game time.
