Firer Systems Down & SLAMs

In a pickup game at DundraCon this weekend, we had an unusual 
situation occur.  A SLAM fired at target vehicle.  It took out the 
target & hit one of the secondary infantry stands.  When the chits 
were drawn for the infantry, a Firer Systems Down was pulled.  How do 
we work this?  Since Firer Down invalidates the shot, does a Firer 
Down on a secondary target invalidate the primary hit?	Or does it 
just invalidate that secondary & any following hits?

Also, I know this is just a game mechanic, but it seems strange that 
ECM & PDS would prevent a GMS system from going down.  Chits are only 
drawn if a GMS missile gets past ECM & PDS.  If they stop the missile, 
then they also eliminate the chance of the firing system from going 
down.  I guess this is the same with all weapons, but for some reason, 
I just noticed when trying to counter 5 GMS/Hx3 vehicles.

Thanks,
Nils
