noun / verb
curb
KURB/kˈɝb/
A raised boundary that holds something within limits.
A raised concrete curb separates the sidewalk from the street.

Etymology
The connection with bending probably underlies the earlier sense “enclosed framework.” That sense extended to the margins of garden beds and then to the raised stone boundary between sidewalk and road.
In context
had him stand actually slightly in the street, so closer to the suspect vehicle, the shooter vehicle, than the actual teenagers were, so he stood a few feet from the curb toward the middle of the street.
