Ban on strafing "civilian targets" in occupied Eur

[Lagarto]

Until when?
I just read that one of 78 FG pilots, Lt. Peter Pompetti, got a written reprimand from Major General Kepner, CO 8th Fighter Command, and was almost removed from flying status, for having strafed a train engine on 6 February 1944, somewhere in Low Countries (does anyone know where exactly?)
With time, this ban was obviously lifted and fliers allowed to target at will anything that moved. Any details on this issue higly appreciated.
Thanks in advance
