Paula-- Few vets smoked dope in the war zone. Those in the cities and on huge bases did more than smoke dope. Yes-- I read about them. Doubt it was due to be in a war zone and also doubt it was due to the medication administered as some lawyers would like us to believe. Now--- how many wives are murdered by their non-vet husbands every day? The 4 you brought up are of how many 100K? Now use the same % on any group you would like, white, hispanic, black, muslim, catholic, etc. Betcha ya'll be surprised!
