call the town officials. You can read to them about flag protocol, but what also works is a letter to the editor. The governor can call for the US flag to be flown at half staff, but usually it is for service members killed on active duty.
The township can have their flag flown as they wish, the fire hall can have their flag flown as they wish, but they cannot order the American flag flown at half staff for whoever they want. It pisses me off, a lot of times it's right wingers who "love" America, but have no idea how you treat its emblems.
Also I have seen schools fly the flag at half staff for students killed in car accidents, it pisses me off. When I try to explain, why the flag should be at half staff, I tell the person I'm explaining it to, that the person being honored must have been an asset to the United States as a whole.
