I focused on fourth paragraph for the third draft. My fourth paragraph is about some ethic questions that led by the surveillance cameras.  In my first and second draft, I did not mentioned much my opinions about the questions I found. For the third draft, I added some of my opinions behind each of the questions to show the readers my point of view and persuade them my thesis. Moreover, I made my topic sentence more specific, but I think I still need to work on later, because that paragraph is not similar with two others. I will ask for more opinions on my question paragraph.
