[12] In an interview conducted by Nikos Evangelatos on Skai TV in May 2012, Kasidiaris declined to condemn Nazi leader Adolf Hitler and stated that "his role in history will be judged in time," and reiterated his stance against immigrants in Greece.

Defending himself in a discussion of whether to lift his parliamentary immunity over his assault of Kanelli, he quoted the passage, "In order to destroy the prestige of heroism we shall send them for trial in the category of theft, murder and every kind of abominable and filthy crime.

[23] On 10 July 2014, Kasidiaris was taken into custody in Koridalos prison, on a charge of weapons possession with the intent to supply a criminal organisation.

[24] On 1 July 2015, Kasidiaris was released from custody after the council of appeals court judges deemed that "the legal weight" of the offense was not adequate to justify detention.

Kasidiaris was required to report regularly to his local police station and under the conditions of his release was not allowed to visit Golden Dawns political offices.

[26] On 18 December 2019, during the Golden Dawn trial, which had started in 2015, the prosecutor suggested that all defendants except Roupakias are found not guilty of murdering Pavlos Fyssas and all felonies.

[citation needed] His candidacy was made official on 10 August and he was registered as a candidate on 10 September for the 2023 Athens Municipal Elections.

[citation needed] On 7 June 2012, during a television appearance on ANT1, Kasidiaris, in response to a verbal disagreement, splashed a glass of water at Greek politician Rena Dourou, and then proceeded to slap Liana Kanelli multiple times after she struck him with a piece of paper.

[33] The heated exchange was a fluid discussion focusing on the rights of immigrant workers vs right of the unemployed Greeks and the development of gas reservoirs in northern Crete eventually disintegrating from a heated debate to broken rhetoric from both sides about opinion on the Regime of the Colonels to the persecution of Golden Dawn activists.

Giorgos Papadakis, a presenter and journalist who witnessed the assault, stated that threats were also made to television crew and other employees.
