Our reading
An editorial interpretation.
The speaker offers a bitter civic slogan, calling Baltimore the place where killing is treated as a minor offence. The exaggeration suggests homicide there is handled as routine, almost trivial, and the dark humour carries a note of weary cynicism about how cheaply lives seem to be weighed.
