1. 10%

2. 20%

3. 30%

4. 40%

The correct answer is: 20%

Systematic neighborhood canvassing shortly after a crime is an important strategy in criminal investigation. Research indicates that approximately 20% of all cases benefit from positive information gained through this method. The purpose of a canvass is to engage with community members, as they may have witnessed the crime or have relevant information that could aid in the investigation. The effectiveness of canvassing is enhanced when it occurs soon after the crime, capitalizing on the potential for fresh memories and observations. By directly engaging with individuals in the vicinity, investigators can gather critical leads, identify witnesses, and acquire other pertinent information that may not be documented elsewhere. This 20% figure reflects the significant role community involvement plays in solving crimes, underscoring the importance of outreach efforts in law enforcement practices. While a higher or lower percentage could suggest varying levels of success in different regions or cases, the 20% figure provides a general benchmark for the positive impact of neighborhood canvassing.
