The previous post mentioned that serial killer Steven Gordon acting as his own lawyer was a peculiarly sociopathic hallmark.
To fully fathom how different a sociopath is, put yourself in that situation for a moment. Imagine that you've committed a terrible crime, your life is on the line, and you need representation. Wouldn't your instincts be to put yourself in the hands of an expert, or at the very least, let one help you? In those circumstances, you need someone who knows the law, who knows the ins and outs of a courtroom, who has some sense of the local judge, and who's familiar with all the intricacies and technicalities associated with legal procedure.
Nah....you can do a better job.
When you board a commercial flight, is your instinct to saunter into the cockpit and say, "You can relax now, fellas. I'll take charge here. Don't worry, I've got this under control."
When you go into a dentist's office, are you tempted to say, "Just hold the mirror for me, I'd feel more comfortable drilling my own teeth"?
When you go for a colonoscopy, do you say, "Hey, don't bother with the anesthesia, I'll just put the tube in and cut off the polyps myself"?
When you see a couple of police officers making an arrest, do you step in and say, "It's okay guys, I'll take it from here"?
The thought of doing these things seems insanely arrogant.
That's the difference between you and a sociopath.
Now, admittedly, even sociopaths don't drill their own teeth, or pretend to be able to fly a plane (Frank Abagnale, upon whom Catch Me If You Can was based, appears to be the rare exception.) But the next time you hear of someone acting as his own lawyer, especially someone with no legal training, keep these analogies in mind.
And be aware, he's almost certainly a sociopath.
