I think his military service should be left alone. I'm sure that he put his life on the line during his military service just like many others did.
As far as present day matters are concerned, that is a different story. I think that Murtha has made some very irresponsible and dangerous comments, and the fact that he did serve in the military should not make him immune to criticism and attack. Stick to what he's doing now instead of dredging up material from years ago that will only reflect badly on those who are trying to make an issue out of it.
It is amazing to me....the folks who have never served in the military...much less being Vietnam Vets...always wan't to give Murtha a pass...I say...WHY...please explain why it is OK to be a liar about your combat record...???
