In 2001 when Houston was flooded, thousands of JW volunteers turned up to help fellow JWs and a few non-Witnesses benefited as well.
In 2002 when Mount Nyirangongo in Goma, Congo erupted JWs sent aid that helped both JWs and non-Jws alike.

And according to the Feb. 15, 2003 Watchtower, under the heading "Life in a Refugee Camp" material assistance has been given to everyone in these camps in Tanzania. See page 16 and especially this quote: "The Witnesses in Europe have collected tons of soy milk, clothes, shoes, schoolbooks, and soap. These items have been donated for distribution to all refugees, in line with the Bible principle: 'As long as we have time favorable for it, let us work what is good toward all, but especially toward those related to us in the faith.' --Galatians 6:10."
Now it is good to see that Jws are offering aid to everyone at times of natural disasters and the displacement of peoples brought about by civil wars, but will the time ever come when they will begin outreach programs and "work what is good toward all" in their own communities? This would definitely be a plus for their tarnished image.
