LINDA ARNDT Well, I have compassion that I bring to work. And compassion is not the same as empathy. Just simple courtesy towards people in this case just went out the window. Just was gone.

ELIZABETH VARGAS Should there be courtesy when people are murder suspects?

LINDA ARNDT Absolutely. I should show you respect. Does that mean I’m bonding with you? No. You want someone to talk to you, you establish trust. You show sincerity. And you can’t fake it, because people know when you’re insincere.
