The accused, who is said to be the "NSU 2.0", stated before the Frankfurt district court that he had not written any threats.

He says it would have been impossible for him to get all the data.

However, the man does not appear harmless.

If only because he bullies in court and insults women, hardly distinguishes himself from right-wing extremist ideas and shows the middle finger.

All quite similar to the style of threatening letters.

The man is accused of having written 116 threatening letters.

They were all read out in court.

Hours full of hate and contempt for human beings, full of sexism and right-wing extremist babble.

Again and again, non-public data was mentioned in the threats: residential addresses, private cell phone numbers, but also names and dates of birth of family members, including the name of a two-year-old girl whom the accused allegedly threatened to "slaughter".

It is still unclear how the man got hold of the data.

The prosecution of the public prosecutor's office in Frankfurt does not even deal with this.

She acts as if this question does not even arise.

As a result, however, the question now stands like a elephant in the hall of the Frankfurt district court.

A fact that the defendant cleverly exploits.

After arresting the man, investigators said he "stole" the data by impersonating an officer on the phone.

Police officers are said to have fallen for it again and again.

That's a bold hypothesis.

And yet it forms the fragile foundation of this process.

The question was never really determined.

Furthermore, it is not clear what connection the police themselves have to the threatening letters.

During the investigation, they quickly came across a right-wing extremist chat group in a Frankfurt district.

A "chance find"?

Data from a Frankfurt lawyer is said to have been retrieved from the computer of one of the participants in the chat group shortly before the lawyer received the first threatening letter against her.

In addition, a later threat to the lawyer also contained her blocked address;

if this had been queried regularly, the State Criminal Police Office would have been notified.

The perpetrator must have found her in another way.

The police officers from the chat group are suspended.

They were never exonerated.

After the arrest of the now accused man, the heads of the Hessian security authorities were visibly happy to have finally found a single perpetrator who could hardly be further from the Hessian authorities: an unemployed, convicted Berliner.

The "entire Hessian police" could "breathe with relief," said Hesse's CDU Interior Minister Peter Beuth.

"According to everything we know today, a Hessian police officer was never responsible for the NSU 2.0 threatening email series." And the right-wing extremist chat group?

A "chance find," according to the special counsel for the case.

That was hasty, and it did not bring any real lasting relief for the officials.

The process now shows this clearly.

The question of a possible connection between the threatening writer and the police arises there every day.

It remains to be seen whether the district court will be able to find answers to this.

The shadow that the case casts on the police is likely to remain.
