My favorite TV show is Criminal Minds. I love crime solving shows and am always very interested in the types of criminals there are and how they are caught. It is amazing how even without technology how people can be so capable of such detailed observation and evaluate and analyze situations to actually solve crimes. Then we add technology to the mix and things get even more amazing. How we can get a sample of dirt, or a single hair or fingernail clipping and figure out where it came from or what its components are, even DNA.
