I see it all the time and it's interesting that someone has given it a clever name.
For example (thankfully the number of people that I know who are climate change skeptics has dwindled hugely in the last year or two):
- the world isn't warming at all
- anyway if it is warming, it's not because of human activities
- and even if it's caused by human activities, its effects will minor
- and even it it's happening, and it's caused by human activities and its effects are going to be serious, it's too expensive to do anything about it.
For the sake of argument, assume all those things are true. That's a perfectly reasonable argument to use in a court situation. When there's going to be a final verdict, from which appeal is impossible or very expensive, you are an idiot if you only bring up the fact they were a 1000 miles away. You marshal every argument you possibly can. This isn't a dialog; you don't get a (cheap) response once the verdict is in.
I think this is a poor essay, blaming a standard argumentation technique for the poor behavior of certain industries. The problem isn't the four dog defense, the problem is the poor behavior of certain industries. I mean, remove the defense from those industries and what would change? Basically nothing; one would have to be some sort of very specific meta-contrarian cynic to claim otherwise. Clearly it's not the real problem.
Also, it's not the "Doggy-Dog World of Politicians"... it's the "Dog-Eat-Dog World of Politicians". I mention this because frankly it struck me as on par with the quality of the rest of the essay. Edit: In fact, on reflection, I've flagged it. It hasn't got much redeeming value.
This is about when your client did kill a person and you're using a slowly receding circle of lies to try to give them as much time as possible to skip town.
Blaming this defense is like blaming the fact that some companies are bad actors on the fact that they are using syllogisms. It's not the syllogisms. It's very weak thinking to think it could be. The problem is not the "four dog" defense, it's the bad actions themselves.

It’s very real.
