In 2011, Lithuanian authorities had initiated prosecution against Paleckis for his alleged denial of Soviet aggression against Lithuania. As part of his journalistic research, Paleckis claimed he had found several witnesses and ballistic assessments that seemed to indicate that there were secret snipers on the roof near the Vilnius TV centre who were shooting civilians. He then went on to state publicly that “it appears that in January 1991 our own people were shooting at their natives”. A Vilnius court had vindicated Paleckis in January 2012. The prosecution had appealed, and Paleckis was sentenced to a fine of 10,400 litas on June 12, 2012.
He was arrested again in 2018 for spying for Russia.
