law - A discussion with state security

ESWN publishes a nice account of an interrogation of a citizen of Wuhan by officials of the Shandong state security.

The national security bureau people were quite polite. The Wuhan people did not take part. The Shandong people held good attitudes, and they were professional.

That complies with accounts I have recently heard from others who had talks with state security. They actually complained that Chinese citizens would sue nowadays everybody, if they thought they were treated badly, including state security, making them rather careful in avoiding possible suits;
The detained citizen gave the account and ESWN summerizes the techniques:

They just kept asking the same questions again and again. It is as if they had written down the list of questions that they wanted to ask, and then they jumped back and forth and asked similarly phrased questions for the purpose of looking for inconsistencies to invalidate your truthfulness. It was very exhausting!
They would also switch out your concepts -- for example, when I said "If someday the ban on political parties is lifted, we can form political parties", the interrogator changed it to "You want to establish a political party!" As another example, when I said "Democracy can only be possible when the people unite," the interrogator changed it to, "You want to establish an organization to bring people together."
And they also make leading statements. For example, they say "Talk to us how about you
and XX are establishing a political party." There was nothing about establishing any political party before this, but they act as if this supposition were true and want you to describe how you intend to proceed.

What we are still missing is state security maintaining their own weblogs, but that seems a matter of time;
