If you shoot someone in Chattanooga and they die, there's a 62% chance that police will arrest you. If you shoot someone and they live, the chance that you'll get caught or that the case will be cleared drops by about half, to 33%, according to a Times Free Press analysis of shootings since the start of 2012.

The data show 184 shooting incidents in which 191 people were wounded and 27 people were killed between Jan. 1, 2012, and Tuesday.

With Mayor Andy Berke's plan to add manpower to the police department, police Chief Bobby Dodd hopes to improve those arrest percentages.
