Question: What other voice acting has the actor that voiced Aquaman done? Passage:Aquaman has guest starred in several episodes of the animated television series Justice League and Justice League Unlimited, where he was voiced by Scott Rummell. This version was based closely on the hot-headed antihero persona (the producers were aiming for "Conan underwater") of the 1994 and 2001 Aquaman comic book series, with the Viking-like appearance and hook prostheses. Here, he sacrificed his hand to save his infant son from being killed in a plot against his life by his evil brother Orm; Aquaman and his son were chained to a rock that was falling towards an underwater magma flow, and Aquaman only had time to free his right arm from his chains before cutting off his left hand to escape his remaining bonds. In the season two episode, "Hereafter", he is listed as a member of the Justice League on the Watchtower database after Superman was sent into the future. He later appeared in an homage episode alongside Superman, Batman, and Wonder Woman that pitted them against the Ultimen, modern pastiches of Samurai, Apache Chief, Black Vulcan, and the Wonder Twins from the Super Friends (Wind Dragon, Longshadow, Juice, Downpour, and Shifter, respectively). According to the website Television Without Pity, producers created Devil Ray and removed Aquaman and Black Manta from the series before the episode "To Another Shore" because the rights to Aquaman were no longer available due to an embargo on the characters because of the proposed and unaired Aquaman series.

Question: What is the population of the city Ed Ou was attempting to travel to on October 1, 2016? Passage:On October 1, 2016, U.S. Customs and Border Protection officers detained and questioned Ou for more six hours in the Vancouver International Airport on his way to cover the Dakota Access Pipeline protests for the Canadian Broadcasting Corporation (CBC) as part of a project on Native American healthcare in North America. Ou's intended destination was Bismarck, North Dakota but, after passing through the initial security line at the airport, he was flagged by custom agents for secondary screening and pulled aside. They questioned his purpose for traveling to the United States and when he last visited Iraq, a routine experience for him as a journalist reporting in dangerous regions. He explained that he was on assignment as a photographer to cover the pipeline protests at Standing Rock for the CBC and that he had not been to Iraq in more than a year. He was then detained in a room where he was asked to provide details of his trips to every country he had visited in the last five years and all extremist groups he had come in contact with. Officials then requested that he unlock his three encrypted cell phones to search for images of him "posing with a dead body". After he refused to comply to protect his sources, they denied him entry into the United States, confiscated his phones and other materials, searched his checked baggage, and made photocopies of his reporter's notebook and personal diaries against his wishes. When his phones were returned to him, there was evidence of tampering with the SIM cards suggesting that copies of them may have been made. A border official later stated that his name matched a "person of interest" on an unspecified U.S. federal law enforcement watch list, however, no official reason was provided for his detention aside from it being "classified". Ou's travel rights into the United States have been revoked.
