That's backdrop. Relevant here, North and South Memphis are largely the worst in terms of violence. You do not want to be in certain neighborhoods regardless of color. Even cops avoid them. Others are a risk more if you're white or look like you have property to take. Local media & cops suppress the worst of it to maintain tourism revenue (eg Elvis, BBQ) although the murders naturally get reported. Examples of censorship were kicking out The First 48 show and rape kit scandal. That Google Maps takes you right near those areas is probably why lots of people think the whole city is hood and trashed rather than just those parts. They never see the good parts unless specifically visiting them family, friends, jobs, or tourism.
So, yeah, it's a real issue. I double-check Google Maps if I'm going anywhere Downtown, Midtown, North, or South as it doesn't differentiate risky vs non-risky areas. I regularly have to force it to make safer routes. Straight-up avoid certain areas of the city unless I'm packing heat & with backup. Otherwise, still all kinds of good things to get involved in over there with most folks being alright. We just in a rough area and economy. :)
Note: As another example, BLM protestors sieged our Interstate (I-40) last night for hours then dispersed into Downtown. Local news cautioned everyone to stay away from that area for safety as it's normally dangerous but now unpredictable. Bad route at the least. Google routes still offering me a speedy trip through there, though. Unreal.
