When you don't immediately release any homicide suspect or victim information, then nobody in the area is going to bother to call in what what they might have seen. The longer you wait, the less likely they will want to get involved. If they know the victim, then they may be more likely to give information in the hours after a shooting. LPD had 80% clearance rates and now you have below 50%. They had Captains between homicide and the chief's office who kept politics out of police work, unlike today.
