Google employed questionable and misleading methods for the project, dispatching teams to target homeless people, along with students on college campuses around the country... A third party employment firm called Randstad allegedly paid the workers, who claimed they were instructed to go after people of color, conceal the fact that they were recording people's faces, and even lie to maximize their data collection... "We were told not to tell (people) that it was video, even though it would say on the screen that a video was taken," [said] a worker... Google immediately pulled the plug on the program and ordered an investigation... Google said that it instructed its contractors to be truthful and transparent with volunteers in the study and that they should obtain consent and ensure the people they interview are aware of why Google was collecting the data.
