This matches the MO of thieves probing with the intent to gain entrance to a residence for the sole purpose of robbery, assault, rape, and murder. I have been present at homes that have been the recipient of these late-night "Knock on the door, looking for help", and we proved it was nothing more than probing to see what the response would be. (Note, neighboring residences were broken into and robbed when the knocking got no answers).
We also hear about white folks getting stuck in "da 'hood" and beaten simply because "dey ain't frum arund hea!".
It's a shame it's come to this, but you reap what you sow...
Didn’t think of that...
what would likely happen to a young white woman going door to door asking for help in a “black neighborhood”?

Quite right.
