People talk about Central being "dangerous" or whatever but it's all bark and no bite. There are certainly unhoused and unemployed people hanging out and making noise/minor disturbances, but violent crime is fairly rare. On the rare case that it does happen, it's generally between people who know each other and doesn't involve random strangers/tourists.

Keep your wits about you, know where you're going, and mind your business and you should be fine.
