Germans: We Put White Flags on Brooklyn Bridge Artists say they were surprised by strong US reaction By Newser Editors and Wire Services Posted Aug 12, 2014 6:11 PM CDT 58 comments Comments One of the white flags on the Brooklyn Bridge, July 22, 2014. (AP Photo/Richard Drew, File) (Newser) – Two German artists have claimed responsibility for the white flags that mysteriously appeared on the Brooklyn Bridge last month. Mischa Leinkauf and Mattias Wermke said today they removed the bridge's American flags and posted the white flags early July 22 in celebration of public art. They say July 22 marked the 145th anniversary of German-born bridge architect John August Roebling's death. They say they're returning the American flags. Police say they're aware of the artists' statements but won't say whether investigators had identified them as suspects before they came forward. Deputy Commissioner Stephen Davis says the investigation is continuing. He says detectives are trying to determine if more than two people were involved in the flag switch. The artists told the New York Times that they didn't get much attention for similar projects in other countries, and were surprised by the strong US reaction to the flags.
