Summary: Wael Abbas is an Egyption journalist/activist who began documenting protests in Egypt in 2006, including multiple examples of Egyptian police brutality, which he would then upload to YouTube.

In 2007, after posting a few explicit examples of Egyptian police brutality, he discovered that his entire YouTube account was shut down, taking down 181 videos covering not just police brutality, but also voting irregularities, and street protests. At first YouTube refused to comment on this, and only told Abbas that the account was shut down due to multiple complaints about the content.
