And you can do something about it.
When you see anyone underage being prostituted (doesn't matter if they are smiling, speaking crudely, dressing provocatively, addicted or not), they are a trafficking victim.
When you see anyone being prostituted no matter what their age if there is evidence of pimp control (car pulling up and several people getting out to work the lot, talking about making a quota, calling a third party to report their earnings, branding on the victim, etc.) this is human trafficking.
Make the call, save lives!
