One Tree Hill - Karen blames Dan for Keith's death

KAREN: I was going through Keiths belongings and I found some things I thought you should have. Things that might mean something to you. The adoption papers that filed for the child that YOU abandoned. Invitation to Keiths wedding. His wedding to Jules that is or Emily or whatever the hell her name was. The wedding to the hooker that you hired to seduce your brother. Keith Scott Motors. He loved that place. At least until you swindled him out of it.
DAN: Karen...
KAREN: You killed him. You may not have pulled the trigger, but you let him go into that school.
DAN: Karen, I had no idea Keith was going inside. I was trying to keep everyone safe. I had responsibilities as the Mayor
KAREN: RESPONSIBILITY AS THE MAYOR?! WHAT ABOUT YOUR RESPONSIBILITY AS A BROTHER?! WHAT ABOUT YOUR RESPONSIBILITY AS A FATHER?! YOU HAD TWO SONS IN THERE DAN! Where were you for them?! While Keith was lying there dying Where were you? I wish It had been YOU who died in that school.
