Guns in Close Combat

There is also a penalty to your

rolls for using guns in melee combat. Down the operative tree there's

an ability called Sharpshooter. If you're of-level and had the memory

slot, keeping that ability loaded will negate the guns in melee combat

penalty.

Does sharpshooter really help when you're in interlock?  I thought it was only for when you were out of side of interlock and shooting at an enemy who was in interlock with someone else?
