A Must Watch Video! Chinese police molesting, an African woman deemed her to be a prostitute

I don't really know what this African Lady did, to deserve all these beating and molesting, should I call it Racism or gender inequality, or exercising authority from ones land to intimidate foreigners. I salute the African Lady's courage to speak out, even in the face of high intimidation. Please this act should be looked into, as this is a terror to other foreigners wanting to visit China, and it can ruin the good relationship between the Chinese government and Africans as a whole. If the police wants to do their work, there is an appropriate way to investigate not the other way round. I am pleading to the Chinese authorities to check the activities of those representing them, especially ,there police men. Because Africans , Love Chinese so much and wouldn't like wolves in sheep clothings to deter it.
