Yea, too slow clearly. But it's an old woman and a child so I wouldn't expect them to move much faster. They're incredibly lucky that they got to the door at least. The dog and the bus honking might have been enough to scare the nigger this time. They relaxed, but eventually realized the danger.
They had like, over 10 seconds to do something.
Not victim blamin', but dey gotta be quickah den dat budfy.
