True. Several studies have shown that decreasing response time can increase the clearance rate. The clearance rate is the percentage of reported crimes that are solved by police or other law enforcement agencies. By responding more quickly to a crime, law enforcement officials may have a better chance of apprehending suspects and gathering evidence before it is lost or destroyed. This can improve the chances of solving the crime and increasing the clearance rate. However, it's worth noting that there may be other factors that affect clearance rates as well, such as the quality of evidence and the resources available for investigations.
