Many people on these forums talk as though they do. I guess you have to live here in an ordinary neighborhood to get a good grasp of things. Like all places, you get your poor areas where desperate people take desperate measures and make all the headlines.
Most murders are gang members on other gang members. By far the most dangerous thing here for your average joe are the useless drivers who don't use their turn signals, and pedestrians who don't bother to look before crossing because they have right of way and are too busy messing with their phone to pay any attention to anything around them, this somehow extends to cyclists too, who are supposed to stop at stop signs like all the other vehicles on the road, but rarely do.
