I love the bullshit argument, "Serial killers are rare today." No... they're not. The only rarity, my friend, is any intelligent argument coming from our opposition. Most sk's purposefully expose their own crimes 1 day after it or possibly more. Send letters to police to taunt and provoke, etc. Then everyone knows it, bam! But if we didn't, the cattles would only discover the crime/s 5 or 10 years after. They really think we're normal people. We're chameleons. We can adapt at any modernity, and believe me, "veteran" serial killers will still kill in our modern world. Bottom line.
