Passage Summary: A shop owner thinks crime isn't scaring away customers because the people currently in the shop say they aren't scared.

Conclusion: Crime is not negatively impacting the store's business by deterring potential shoppers.

Reasoning: The owner spoke to current customers, and those customers reported that they are not worried about crime in the area.

Analysis: This is a textbook case of 'survivorship bias.' The owner is only surveying the people who actually made it into the store—the ones who clearly weren't deterred by crime. He is completely ignoring the potential customers who stayed home specifically because they were afraid. It's like asking people at a steakhouse if they are vegetarians and concluding that no one in town avoids meat. Look for an answer that points out the owner's failure to sample the very group of people relevant to the conclusion: those not currently shopping.
