“I saw a lot of police activity on the streets making sure everything is safe,” says Joe D’Alessandro of the Convention and Visitors Bureau. “I saw internal security people from Oracle.”

“I can’t give you our tactics, but we are prepared for incidents like that,” says Linnane. “We’ve had the incident active shooter at UPS. We have had other incidents smaller ones which are prepared for and we trained for.”

In the case of a shooter in a hotel, there will be extra staff on hand.

“Whenever a situation like this occurs, the security in hotels and other places take extra guards to make sure that there are no copycats,” says D’Alessandro.
