I didn’t get the “unsafe” vibe from Berkeley’s campus at all when I visited or from relatives’ experiences there from the late 70’s to the present.
And comparing it to run down areas of NYC is laughable…especially considering I am a New York native and my childhood/early teen years coincided with the tail-end of NYC’s high crime era in the 1980’s and early-mid '90s. It’s like comparing apples to durians.
