Just a thought:

You know how chemicals claim to kill 99.9% of bacteria? Well there’s always that 0.1% that was adapted enough to survive and it will reproduce more well-equipped offspring which is why antibiotics are being produced at very high “strengths” to combat this “smarter” bacteria.

Well, when criminals go to jail and come out after a short amount of time, they, in a sense, can help others figure-out how to be sneakier and more cunning than in the past. Also, Think about this: criminal investigation shows not only are a good way to show viewers an inaccurate depiction of the investigation process but also a cornucopia of checklists of details criminals should mind to get away with harmful acts.

Yes medicine/technology is getting more advanced but so are pathogens/criminals.
