Why does the corner store that does not have a video camera vulnerable?

The store is in danger of being robbed as well as other things.

Explanation:

When a store has a video camera and they are robbed, they can use the evidence in the video camera to catch the robber. In this case they can get money back and send that person to jail to prevent future robberies of other people and themselves. But, without the video camera you have no evidence of who your robber was. This causes you to ony lose money and put you at higher risk for being robbed again if the perosn knows they can easily not be caught.

i will try let me see what they are first

in ray bradbury's short story "a sound of thunder", mr. eckels's fearfulness leads to drastic consequences for the rest of the world.

in the story, mr. eckels, who is a hunter, hires a time travel company to travel to the age of dinosaurs. although he is excited for the hunting expedition at the beginning, when they reach there and mr. eckels sees the tyrannosaurus, he feels frightened. as he is afraid of the tyrannosaurus, he steps off the path although he has been warned not to do it. by stepping off the path, the entire course of the future is affected: mr. eckart alters the future by stepping on a butterfly, which causes a new man to be elected president in the future. in that way, it is mr. eckart's fearfulness what triggers 'the butterfly effect' and what leads to drastic consequences for the rest of the world.
