I need to make myself clear.
There is potentially a harassment case with the Guard pushing Farah. However I personally cannot see racism, then only evidence we have is the video in which the guard pushes him along and Farah complains about a previous incident of touching up without giving anymore details about it. So I’m not accusing him of lying, rather more like being slightly over the top. The security guard should have not pushed him, and should have instead asked him to stop filming (if that is airport policy) and move along.
