"Reminiscent of 9/11, you go to your work and don't come home," said Leeann Good.
Good is a Navy veteran and she's been on that Washington, DC naval yard before, where authorities say former Navy reservist Aaron Alexis shot and killed his own.
"I think it is the most atrocious crime that could be done against the government," said Good.
Authorities say this area is highly secure, but Good, has a much different opinion.
"I personally don't believe that to be true," she said.
Good claims, when visiting the base shortly before 2001, security seemed very relaxed.
But, Good also doesn't know how the shooter managed to have a weapon there.
"This is more of an administrative base with offices, typically all the people you see with guns are the military police," said Good.
Good even says her other Navy veteran colleagues, who have visited the DC yard recently, also agree.
"He says that it is not highly secure, it is not top secret security," said Good.
Perhaps the most frightening thing for this veteran is the feeling that safety on home base is gone.
"Your people are there to protect, everyone, the civilians that work on that base should just as safe as if they were in their own homes and obviously that is not the case as we have seen this morning," said Good.
