As the next anniversary comes around this month, I’m just going to update this thread with some previously undiscovered material related to this event.
A excerpt from a French news segment detailing the scenes within government station MBS-4 in the midst of the unrest happening at that time. The video was dated by OP to be on 02/27/1986. This might not help much but it does make a very good reference have we found actual recording of the local TV stations from within that era.
