One of those "what would you do?" moments is sparking national outrage.
Philadelphia Police and Child Welfare officials are investigating a disturbing video is posted on social media.
It appears to show a young girl trying to awaken her mother- who seems severely impaired- while the two take a ride on SEPTA.
The woman who appears to be in her 20s or 30s is seated just behind the rear door of a route 66 SEPTA trackless trolley along Frankford Avenue. The video appears to take place during daytime, but what day, is not clear.
The woman seems to be impaired, and her daughter, the little girl in pink at the right who appears to between the ages 5-7 years old tries in vain to roust her from her stupor.
We've blurred the images, to protect the identity of the little girl and because the mom has not been charged with any crime. There's no sense that the person taping this tries to help, and the folks seated around the mother and daughter as well as those squeezing past to get off the trolley also seem to ignore the situation.
Ultimately, the woman was reported to the city's department of human services by those who saw the video online, which prompted this response from DHS.
They say the woman in the video "appears to be severely impaired by drugs or alcohol."
Then comes this rebuke, "while it's helpful that so many people emailed and called us after viewing the video, there were many people on the bus (trolley) who witnessed this as it was occurring and took no action at all."
SEPTA says it received no report of the incident from its operator, but a spokeswoman says it's not clear that operator knew what was happening.
This was not a noisy confrontation up front of the vehicle, but, in fact, happened quietly near the back.
SEPTA, too, wonders why no passenger stepped in to help the little girl or her mother.
