Do you think crime shows help criminals get away with crimes more often?

Mo
Recently we had a debate in my criminology class about crime shows helping criminals to make sure that they didn't leave any evidence behind. Kinda like how you'll see on Law and Order SVU a lot: "The perp wore gloves, a condom, a mask... traces of spermicide were left behind, we haven't gotten back the forensics from the Vic yet." Etc etc. People were very 50/50 on it. 
Do you think some of the details discussed in crime shows about forensics and evidence help criminals to get away with crimes more easily, or do you think the info about forensics/evidence is easily accessible anyway and the shows aren't really an issue?
