We can call, email, write to our Federal Local Members, Alex Downer and of course the PM demanding that our Government exert every pressure on the Indonesian Government to proscribe, to ban, J.I. At present, J.I. is a legal entity. Being a member of J.I. is not illegal. As I read somewhere earlier, only international pressure on the Indon Gov't will result in J.I. being banned.
So, DO IT!!!!!!!!!! It's all very well moaning & groaning - DO something!!!
