Columbo used many new forensic techniques and high tech apparatuses that helped solve the crime and would not solve a crime today. Remember he introduced the Selectric typewriter and caught the killer because of the cartridge ribbon. Killers wouldnt be caught dead with a selectric typewriter today. He introduced the fax machine...now why would a guy fax a joke to his wife if he was planning a suicide. YEP, gotta be murder and the killers print gotta be on the paper. He intro'd the answering machine to get a greedy developer. He showed us a 50 lb cell phone and his understanding of the blackout zone caught Shatner in Shades of Grey. Today the cell phones know what we're plotting and have it recorded before we finish dialing. Let's not forget the fancy cigar cutter. Ah yes, we could go on and on.
