Narrative:

During VFR simultaneous approachs to 19L and 19R, approach vectored us on final for 19L directly abeam an large transport for 19R. In view of the local terrain, if the other aircraft had to go around on less than a 2 mi final, he would have to turn into us for terrain avoidance. Due to inability to stagger our approach spacing we elected to perform a missed approach.

Narrative: DURING VFR SIMULTANEOUS APCHS TO 19L AND 19R, APCH VECTORED US ON FINAL FOR 19L DIRECTLY ABEAM AN LGT FOR 19R. IN VIEW OF THE LCL TERRAIN, IF THE OTHER ACFT HAD TO GAR ON LESS THAN A 2 MI FINAL, HE WOULD HAVE TO TURN INTO US FOR TERRAIN AVOIDANCE.
