Me being an arm chair detective and an even better arm chair CSI I was perplexed by the fact that the head guy of the CSI team sprayed luminal on a suspected blood stain in a pretty well lit room which in every The First 48 episode Ive ever watched they used darkness and a UV light source to show the suspected blood and I didn't see any source of UV light to luminous the blood in this episode which is INFURIATING to me based on the fact that the entire show is based on the collection of forensics and to have the simplest of test being done incorrectly by the head of the department is unforgivable.. There should be no f-ups when it comes to shows like this.. I hate when Criminal Minds continues to call the "unsub" (unknown subject) an "unsub" even after they've learned the "unsub's" identity or how I've seen a few characters handle evidence without wearing gloves..
Your making shows based on the professional collection of evidence how about being a little more professional by making sure it's collected correctly.. Two shows in and I'm out on CSI.!
