And now, a few common misconceptions (mainly fingerprint related, apparently ). So they are some things you might consider when planning your perfect crime (though if you seriously consider the first one, ewwww):
-edit- put in spoiler since it was kinda long. May work on the actual perfect crime portion a bit as well at some point in future.
I could go on, but I grow bored. The perfect crime is the one that you yourself are investigating. By interfering with the collection of evidence and systematically destroying all that is found, you can more or less bring an investigation to a standstill. Naturally, this would work much better in an area where there are fewer police and crime scene technicians so your responsibilities would increase accordingly. Granted, this is still far from perfect. I guess I just like the idea of this kind of thing, you know? Police officer breaking the law, arson investigator starting fires, psychologist that encourages and drives people towards insanity. I guess I like any excuse to be cynical.
Otherwise, the more complex a crime, the more disastrous the results.
While it is easy to say that the Zodiac Killer committed the perfect crime in that they didn't get caught, it is important to remember that there have been astronomical advances in forensics since the killings. Jack the Ripper was also never caught (to anyone's knowledge), but things might not have turned out so well for the fella in this day and age, or even in the '70s. Anyhow, the Zodiac killer left plenty of evidence behind. Given enough manpower and resources, would their luck have remained? That someone does not get caught does not necessarily speak to the chance that their crime would result in conviction, and I think the latter is a better metric for how "perfect" a crime is. There are far too many imponderables related to actually "getting caught" or being identified as the perpetrator. If the police have no case, it doesn't even matter if they know in their guts that you are the guilty party. On the other hand, there might be a crime scene where the perpetrator bled all over the place, rolled around in paint and put his hands all over the walls, vomited a very unusual breakfast, left a note for police with very distinct handwriting, accidentally shot his foot (thus having to go to the hospital), driven his pickup through the living room (leaving muddy tire tracks everywhere), and so on and so forth. If the bloke doesn't get caught, then can we really say this is the perfect crime? He has clearly left behind ample evidence that points very directly to a suspect, the only problem is that the suspect is unknown. The problem with serial killers isn't a lack of evidence, it is the apparent randomness in choice of victims which makes it difficult to come up with a viable suspect or a strategy to more or less catch them red-handed. I'd say that serial killers, the Zodiac Killer included, leave far too much up to chance for any of their crimes to be considered perfect. It's like monkeys with typewriters and Shakespeare. Eventually, one bastard is gonna get lucky.
Of course, there is a great deal of fascination and myth surrounding serial killers. To an extent, they embody humanity at its darkest. Most of us don't just wake up and say "I'm going to kill someone", get dressed, kiss our wife good-bye, and do just that. There is something both deeply compelling and repellent to the notion that fuels the desire to understand and know more about just what makes these people tick, almost as if this can tell us something about ourselves. The attention is largely undeserved in my opinion. These are not mysterious authority figures, some kind of godheads to be marveled at from afar. They are sickness, but they're still human.
Of course there always will be crimes that won't be solved, those aren't really perfect crimes though. It is just that there are limitations to the ability of those that are trying to solve the crime.
Precisely.
Steal some Nee-chans panties Mission Impossible style.
But at what cost? Jumping up and down like a maniac on Oprah? Hardly seems worth it.
Tor services via Bitcoin are often honeytraps or scams. The Hidden Wiki has a decent verified list, but come on, how much can you trust a site asking for payment of a service over the internet, when you have no way to reprimand the person for not following through?
I must admit, the notion of a list of verified Bitcoin-accepting Tor mercenaries was good for a laugh.
