LAST EDITED ON May-17-03 AT 09:26 AM (EST)
 
I think what we are seeing here is Steve Thomas, Narcotics Detective. He arrested people who were buying drugs, selling drugs, or were just caught with drugs. To him, arrest was synonymous with guilt.

When he made the switch to homicide, it is clear he never understood what was evidence and what was not.

edited to change "homocide" to "homicide". I don't think ST ever worked in "homocide".
