Harsh accusation against the incumbent government were heard at a support rally for Croatian war veterans which began in the southern Adriatic city of Split around noon on Sunday ended shortly after 1 pm.
Protesters demanded the release from custody of all veterans pending trial.
"We ask that 350 veterans be released immediately, pending trial, as those people would have never committed crimes had the Croatian people not been exposed to aggression and genocide," former special police commander Zeljko Sacic said at today's rally.
Sacic also requested that a judge and a judge-juror at trials against veterans also be veterans as only they know the suffering that took place in 1990.
He called on President Ivo Josipovic who is a highly skilled jurist criminal to get involved in drawing up amendments to the procedural law.
The protest rally ended shortly after 1 pm after one protester near the stage fainted, police said, adding the 66-year-old man died in hospital later.
The rally was organised by Homeland War associations from the town of Kastela.
