That pretty well sums it up. UK site, but the same principles apply in America.

if you're dirty for something and mentally slow enough to get tangled up by that old knuckle dragging copper on the street
The problem is that the guy interrogating you is not the knuckle-dragging cop from the street. You get a couple of detectives who typically have done hundreds of "interviews" in their career, many more than you, I'll bet. By the time they have done several interviews, plus their training, they know what works and what doesn't, and often their objective is to lock you up, not to achieve justice. Therefore, by reading your broad generalizations of police detectives (knuckle-draggers), I was able to deduce that you underestimate police interrogators. I have spoken to many police detectives, such as my father, who is a retired detective, and his friends, and I can assure you that they are not "knuckle-draggers".
So yeah, you can take a gamble in a police interview if you want to, but I don't really see the purpose. There are really no benefits for you to talk to police without a lawyer present, only disadvantages. So why would you want to do that? Just get a lawyer. If you don't see the wisdom in that, then I would advise that you "Don't get in a battle of wits if you're unarmed". Not having a lawyer present seems a little masochistic to me. You would be stacking the odds in the police's favor. I don't think that you could find a defense attorney in the nation who would advise you to talk to the police without a lawyer present. It doesn't matter who you are or how intelligent you are. The fact that you disagree with that advice tells me that you underestimate the effectiveness of police interrogations.
Defense attorneys deal with police interrogations all of the time, and I am parroting their advice. They collectively have more experience with police interrogations than you or I. They would advise everyone to have a lawyer present during any police interview. Not just stupid people. Everyone. Even defense attorneys that are under investigation. I have confidence in defense attorneys' collective estimation of police interrogations, so I heed their advice. The fact that your statement basically says "only stupid people need defense attorneys present during interviews" combined with your generalizations about police interrogators (knuckle draggers) is what leads me to the conclusion that you underestimate the effectiveness of police interrogations.
It is true that I have limited experience with police interrogations (only seen a few). Because of this, I parrot the advice of those who do have experience and no ulterior motive. That would be defense attorneys. There is the reason that Americans have the right to have an attorney present, and I (along with almost all, if not all, defense attorneys) suggest that you exercise that right if you are ever in that scenario.
