[1] His family were Partisans in World War II; his father was subsequently a professional truck driver and his mother a homemaker.
[4] An opponent of Slobodan Milošević at the congress, he was subsequently a candidate of Vesna Pešić's Civic Alliance of Serbia in the 1992 Serbian parliamentary election, appearing in the thirty-third position on the party's electoral list in Belgrade.
Omerović was a founding member of Social Democracy in 1997 and appeared in the second position on the party's electoral list for Kraljevo in the 1997 Serbian election.
[13] Social Democracy split into two factions in May 2001, after Omerović and several others accused party leader Vuk Obradović of sexually harassing a female colleague.
[14] Omerović became secretary of the anti-Obradović faction and successfully petitioned the Serbian justice ministry to recognize Slobodan Orlić as party leader pending a resolution as to which group held the legal right to the name.
In August of that year, he stated that Albanian terrorist groups in Kosovo were undertaking ethnic cleansing against Serbs and other non-Albanians and urged the United Nations Security Council to take meaningful action to ensure "the disarmament of all those who have weapons and unlawfully carry them, as well as the undertaking of measures to protect all ethnic communities, especially the Serbs.
[28] In September 2007, he accused the rival List for Sandžak alliance of creating an "international scandal" by banning a FoNet journalist from an event in Novi Pazar.
He was quoted as saying, "The perpetrators of the act are unknown, while the police have said that they will suspend the investigation, and have advised Muslims in the area to simply put bars up on the doors and windows of buildings where ceremonies are performed.
In January 2010, Omerović encouraged the Serbian parliament to pass a resolution on the 1995 Srebrenica massacre as a means of promoting reconciliation in the region.
[41] Omerović strongly opposed a 2011 bill allowing members of the Axis-aligned Hungarian Army in Vojvodina during World War II to claim compensation or restitution for properties nationalized by Yugoslavia's communist authorities between 1945 and 1968.
[44] He paid tribute to veteran Serbian human rights activist Vojin Dimitrijević following the latter's death in 2012, saying that Serbia had "lost a great man, a big fighter for civic society and for the state of law in which there would be no second-class citizens.
[47] Following the election, he supported a government bill to criminalize unauthorized participation in international conflicts, saying, "Given the recent experience of several young people, Bosniaks from Sandžak, participating in the Syrian conflict and returning homes in coffins, we assessed that it was the right moment for Serbia to introduce this criminal offence so that all those who do this in the future are prosecuted for it.
[50] During the 2016 parliamentary election campaign, Omerović condemned Sulejman Ugljanin for requesting that the United Nations Security Council send international forces to the Sandžak to "protect the Bosniak people in this part of Serbia."
Omerović was quoted as saying, "Ugljanin has in the crudest possible way abused the [Bosniac National Council], put it into the function of his sick desire to preserve a bit of some sort of power, at the cost of spreading fear.
[53] Omerović resigned from the assembly on 17 July 2018, after having been arrested the previous month for failing to pay for cosmetics at an airport shop in Frankfurt, Germany.
He was also reported to have called for diplomatic immunity on being arrested; this was seen as a source of embarrassment for the Serbian government, but Omerović has said that he never made this request.
[54][55] Fellow parliamentarian Đorđe Vukadinović noted that Omerović had faced strong pressure to resign prior to announcing his decision.
