2006 marked the Baltimore Orioles ninth straight losing season, causing much of the Baltimore fan base to become disgruntled with the team's ownership. A grass-roots movement called "Free the Birds" was spearheaded by Aparicio. For several weeks, WNST aggressively promoted a protest rally that was to take place against the Detroit Tigers at Oriole Park at Camden Yards. The protest was not so much aimed towards the team itself, as it was the club's owner, Peter G. Angelos. According to the Associated Press, during the fourth inning of the game, at exactly 5:08 p.m., Aparicio led a "walkout", with the protest fans leaving the game in unison. The precise time of departure, 5:08, was significant in that "5" stood for Brooks Robinson's number and "8" for the number worn by Cal Ripken, Jr. Many of the protesters wore black T-shirts that read "Free the Birds", a phrase that was chanted loudly through the walkout. Aparicio estimated that 2500 fans were involved in the protest, but the Associated Press gave a figure of 1000. After the walkout, Aparicio was quoted in the AP by saying, "We have a chance to make a memorable civic statement about how we, as fans, are fed up with the embarrassment that the Orioles have become." Peter Angelos had a different take on the rally. "Whoever joins that protest has no comprehension of what it costs to run a baseball team," Angelos said. Referring to Aparicio, Angelos added, "he is a very unimportant person who has delusions of grandeur." In the weeks following the protest, Aparicio created a website in honor of the rally, and declared to his listeners that he would form a union in protest of Angelos and his ownership of the franchise. Aparicio likened it to what "many in the asbestos lawsuits did a number of years ago". "And what could Peter Angelos possibly say to disparage the same kind of union that made him a wealthy man", said Aparicio after launching his website.
Disputes
Aparicio was videotaped attempting to strangle Gordon Keith of KTCK-AM The Ticket in Dallas while covering Super Bowl XLIII in January 2009. The two were separated and police were called. The year before, Nestor reportedly called a member of The Ticket a " Jew" during Super Bowl week. On March 30, 2011, it was reported that Jennifer Royle, a Baltimore sports reporter for WJZ-FM filed a $800,000 defamation suit against Aparicio and two WNST hosts, Glenn Clark and Drew Forrester. Royle, who also worked for MASN, claims that Aparicio and the WNST hosts hurt her reputation with damaging statements about her professional and personal life. Aparicio's lawyer said the accusations are "baseless", and Aparicio denied wrongdoing in a blog entry. Royle later dropped the lawsuit.
