WBRZ - Baton Rouge

BATON ROUGE- More than a decade after the 9/11 attacks, security changes in Louisiana's capital city are hard to miss.

"There's a much greater acceptance in the invasion of personal privacy as a result of September 11," said Joanne Moreau, director of the Mayor's Office of Homeland Security and Emergency Preparedness.

The amount of surveillance and security measures that monitor or investigate people's actions in America greatly increased as a result of the attacks, but more even more stringent guidelines went into place along the Mississippi River.

"There's heightened awareness in the Coast Guard, because all these plants are along the river, you see a lot more emphasis placed on access, ingress and egress to the chemical plants themselves," said Moreau.

The biggest changes came at airports, where passengers had to completely alter how they travel.

"Most of the things you see on those signs are because of 9/11," said Jim Caldwell with the Baton Rouge Regional Airport. "You have to remove your jacket, your shoes, they have the limitation on liquids, so there are numerous things like that, including the restriction that only ticketed passengers can access the secure area."

Part of those new security measures put tighter reins on who was allowed where in aiports. BTR is building an addition to accommodate visitors who aren't allowed beyond security checkpoints, but are waiting for arrivals or seeing loved ones off.
