Pretty sure FD said that turrets in non-forward fire modes could never trigger assault bounties as long as they had a target? Else we may need more info on their logic.Turrets aren't perfect and even if they were any weapon that fired projectiles with travel time would add unpredictability.
Ultimately, it's up to the pilot to have some situational awareness and disengage their weapons when there is a chance of striking unintended targets.
