WDC has been a dump for decades...in many ways. From their politicians, their corrupted police department, their uncivilized residents and so forth...they stink.
I went to DC on a trip from my college in 1980. It was a total crimehole then. We were warned about going out at night and being alone.
I see nothing has really changed. A US Senator was shot in a robbery in 1973
Badly.
