"we do have public displays like the Highway of Heroes, but how are we as a society really honouring our heroes? Shouting “Support Our Troops!” during recruitment drives and yet not supporting them when they return home -- dead...is dishonourable, unpatriotic and a disgrace to any society."

i had to think about your meaning here.

it did function as a challenge for me- 'should i get myself up there on the bridge when the caskets roll through ?'

It's been difficult to do this.  I've lost some kids myself as buns in the oven, and it triggers an element of distance, when i see parents and community members effectively honouring the ongoing throw-away of lives they were fortunate enough to birth.  

My sense is that if I don't know the families personally, then standing on the bridge is simply a political act.  Locally its turning into a situation where professionals feel obligated to show up, whether they know the families or not, to the point where the Legion has to demand space to position themselves on the bridge.

I'm not convinced yet that standing on the Highway of Heroes bridge is in any way a functional duty.

If i know the family personally, then I'd go to the memorial in Trenton or the funeral home visitation.  The bridge is a separate issue- its a socio-political statement on the war.
