It is not disrespectful to the FBI or the government to expect that they play by their own rules. China is being dealt with like an oppressive dictatorship and the FBI is being interacted with like a law enforcement agency in a functioning democracy.
I'm not sure I understand how following American law = disrespect for an American institution..
Is it a slap in the face to use the freedom you have been given?
Would you rather not live in a country where cooperating with the FBI is optional?
