That is totally useless against a mob consisting of two-legged animals.
Situational awareness and planning ahead is infinitely more useful.
Traveling from New York City to Washington DC the first and only time in 1993, I had planned to get off the main highway and visit Philadelphia's historical places. After taking a random exit and traveling less than half a mile I realized that I had not planned ahead. I had failed to identify the known deadly parts of the city. Not the sort of useful information the Visitors Bureau freely divulges.
An illegal U-turn on a major street resolved the consequences of my inattention to detail, but a valuable lesson learned. Philadelphia, for me, will remain permanently unexplored territory.
These [laces that bury their crime stats put a lot of lives at risk by doing so; people unfamiliar with the area can easily end up in the “wrong neighborhood”.
These places need to have road signs like those in “Mad Max”, indicating you are leaving the “civilized zone”...
I hate to pick on the victims but the mother and father should have paid attention to their surroundings. Stopping for gas in a rundown Amish neighborhood is not a good idea for a white family. This family is lucky they escaped with their lives.
