A few years ago there was a vicious street crime in Georgetown, DC, generally one of the safest, most upscale parts of the city. Around the same time there was sudden ‘street crime’ near the National Mall with the monuments, Smithsonian., etc. Pretty much unheard of!
The perps were ‘young people’ who’d crossed town. That was cracked down on REAL fast. The powers-that-be that allow/disregard crime in ‘certain’ neighborhoods won’t allow, and cannot afford, crime in others.
