I was working another sector when I saw this happen and I talked to the RADAR controller involved. I thought it was very very dangerous and I was shocked that it happened so that's why I'm filing a report. LAX Tower cleared an A320 routed south of the north complex runways for a departure into the Manhattan RADAR (MANR) Sector. MANR has control to turn this aircraft and climb them. About the same time maybe a 1/2 mile offset; a CRJ-900 routed north was coming off the south complex. These aircraft have to swap out. MANR was never advised about the CRJ-900 and even though the CRJ-900 was instructed to maintain visual separation; MANR had no idea who that aircraft was. Ninety Five percent of the time a departure off the north complex is immediately issued a south bound heading. In this case the controller waited wondering who this unknown target was (CRJ-900). Had MANR done the norm; and turned the A320 south; there not only would have been an ugly loss of separation but a potential MID-AIR collision. The CRJ-900 would have freaked out if the A320 had turned. Dangerous and Scary! Recommendation; training to LAX Tower on the proper use of Visual Separation; requirements to inform Departure Sector of aircraft using visual and stopped at lower altitude.
SCT Controller observed a conflict event involving two air carrier aircraft departing LAX; the north complex aircraft routed south and a south complex aircraft routed north.
