Based on my experience with a variety of crimes such as stolen cars, homes broken into and assaults (hey...people I know, not crimes I committed!) television shows have completely screwed up peoples expectations of what the police will do to solve a case.
After watching a whole squad of highly trained professionals who apparently never do paperwork all coordinate to chase down a "hunch" from a minor misdemeanor where they get fingerprint matches on their computers in ten minutes and a full DNA test with matching done in fifteen, the average joe expects the same sort of action in real life.
In cases I've been involved in where property was stolen or broken into there were no fingerprints taken. Too expensive, too time consuming and not a serious enough crime to warrant it was the explanation.
Heck, I had a friend who went into her apartment to find a burglar who whacked her on the head and ran. She had to call 3 times to get someone to come over and take fingerprints. They finally did and eventually did identify the guy. About two months later.
I wonder how much this huge gap between tv show inspired expectations and reality affects court cases and juries.
I'm not aware of how TV shows (or the entertainment industry in general) portray crime investigation, so I can't comment on that aspect.
I suppose I can continue to give more background on my specific case. The police department was well-funded and was in a mixed wealth medium sized city in a large metropolitan area. The department was not understaffed. There had been a significant local crime spree going on with stolen vehicles. At least one other local department was trying to crack down on this issue by collecting prints on all recovered cars in an attempt to have enough evidence to increase sentence time if/when the perpetrator was caught.
In any case, a cursory dusting for prints on a car shouldn't take more than 5 minutes or so (from other experience) although the chance of getting a good print isn't extraodinarily high.
It really comes down to circumstance as to how I would expect things to be handled: general staffing, crime severity priorities, and local chronological situations (i.e. massive problem needing to be handled 'now'). And, as with all areas of life, law enforcement has their share of incompetence, poor management, and worse policies regardless of other circumstances.
I do find it disturbing that theft on the scale of an automobile is considered to be nearly beneath the notice of some (many?) law enforcement offices. That, and your story of the burglarized friend. As an old hack penned, "Something is rotten in the state of Denmark."
