Q: Passage: One Meridian Plaza was a 38-story high-rise office building designed by Vincent Kling & Associates. Construction on the tower began in 1968, was completed in 1972 and approved for occupancy in 1973. Built at the corner of 15th Street and South Penn Square in Center City, Philadelphia, Pennsylvania, the $40 million high-rise was built adjacent to the Girard Trust Building, now the Ritz-Carlton Philadelphia, and the front faced Philadelphia City Hall across the street. It was formerly named Three Girard Plaza (see below). The rectangular building was long and wide and contained . Of the 38 floors, 36 were occupiable and 2 were mechanical floors. The structure also had 3 underground levels. The building's structure was composed of steel and concrete and the facade was a granite curtain wall. There were two helipads on the roof. The building's eastern stairwell connected the building to the adjacent Girard Trust Building, known as Two Girard Plaza. At one point there were plans to build a structure to the south of the building that would share one of the elevator banks in the high-rise, but nothing came of the plans mainly because the two sites had different owners. On the northwest corner of the property is a bronze sculpture called "Triune." Designed by Robert Engman the abstract sculpture was not damaged in the 1991 fire and was still there in 1999. The following year the builders of The Residences at The Ritz-Carlton announced that they were considering demolishing the sculpture. In the end the statue was retained and still stands at the location it was originally installed at as of 2014.

Q: 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.
