Tactical Cartography is a powerful way to make social issues more obvious and visible. Revealing a relationship between space and any social concept, construct or problem can help people conceptualize it without any experience. In the example given, mapping security cameras shows people who widespread they are. I was a little confused about what the actual meaning of tactical cartography is, especially what fits into the meaning.
My map is on my computer, and I've had limited success gif-ing it so I'll just show it in class.
