Does a newly freed slave child feel safe living in the South?
I think that more detail is needed in the context of the question. It seems to be operating more in the realm of what can be or a hypothetical situation as opposed to something more tangible or concrete in terms of historical analysis. I would suggest that it would be difficult to conceive a newly freed slave child would feel safe in the South. One can extrapolate this to suggest that many children of challenging economic conditions in 19th Century America would not feel entirely safe. At the same time, many children of color in 19th Century America might not experience the full condition of safety. Finally, I think that a child of color in the South, speaking from the most general of points of view, could feel that their safety would be in general. The experiences of people of color in the South both before and after slavery speak to a condition where safety is threatened. Freed slaves were challenged by trying to formulate a life after slavery. Without much in way of any guidance or assistance, being "thrown" into freedom could as challenging as living with the condition of enslavement. Much can be made to suggest that a newly freed slave child would not feel entirely safe living in the South.
Somewhat. Waaaay back then when slavery was really bad many slaves thought it would be safe to flee to the South. Freedom was not guarenteed though. Usually those who fled got caught by "slave catchers" or they were just sent back to their masters.
