Again, my nana saw first-hand a young guy get shot in playa ancha at 8am and bleed to death on the sidewalk before the ambulance was there (which took a while). Now you wouldn't walk by accident in that neighborhood, but this exists and is not "hype."
Re: mugging/theft, yes you can spot some loners specialized in hit and run with no fight in them and just showing you're aware of them will make them move on, but groups of 2 or more guys who will either try to distract you, or even lock your arms from behind while robbing you blind also operate around here. This is not hype, it's first-hand experience, friends who got robbed, and the local press. Now to some extent you have some of that in most cities in most countries, but you do want to be careful.
