Do the crime shows on TV correctly potray the work of forensic scientists?

Forensic Scientists on tv crime shows portray some realism to the job but are not 100% accurate, it may be a fun job for some and not for others. Alot of what is seen is created/made up to increase the audiences attention and entertain the audience, yet they usually stick to some realistic procedures, such as finger printing and number tags for evidence as well as the need for gloves to prevent print damage/tampering.
