It shall be unlawful for a parent or guardian having legal custody
of a juvenile knowingly to permit, or by ineffective control to allow,
the juvenile to be or remain upon any public right-of-way under circumstances
not constituting an exception to, or otherwise beyond the scope of,
this chapter. The term "knowingly" includes knowledge which a parent
should reasonably be expected to have concerning the whereabouts of
a juvenile in that parent's legal custody. It is intended to
obligate neglectful or careless parents to adhere to a reasonable
community standard of parental responsibility through an objective
test. It shall, therefore, be no defense that a parent was completely
indifferent to the activities or conduct or whereabouts of such juvenile.
