Credit union executives who work in the half-dozen downtown Dallas branches close to where the shooting ambush unfolded last Thursday, which left five police officers dead, are coming to terms with the tragedy that shocked the nation.

What's more, executives said they are reviewing and updating their disaster response plans to include violent, life-threatening or dangerous events that occur outside their branches. 

Safety and security experts said there are steps all credit unions can take to help save the lives of employees and members if a similar shooting scenario were to occur unexpectedly.
