Narrative:

Tower cleared aircraft #1 for takeoff and gave us a heading directly at a traffic watch plane (aircraft #2) that he knew about, just off airport boundary. Received TCASII RA and executed rapid pull-up (climb). ATC advised us that it was his fault and he should have told us about the traffic, TCASII might have saved us.
