> The FBI was granted a search warrant by a judge based on evidence they presented. At the very least this is a process that involves multiple branches of the government.

I'm not sure why that is a justification. The Chinese security services clearly got the authority to act as they did to. It doesn't make it right.

That comment was in response to the previous poster saying the FBI raided the persons house. I wanted to put it in context: the judge agreed to let the FBI raid the persons house based on evidence. There is a system in place to prevent the FBI from arbitrarily raiding people's houses.

It's a justification because they had to provide evidence to a judge who had to assess it given our laws. What better system should I expect? If it's not a system problem and so there's a particular failing in this case, please point it out.

How was the authority given to the Chinese security services? This is a very important detail, because you can setup systems with checks and balances and laws or you can give carte blanche.
