Both can be true. Being the street-level operator for a crime gang isn't exactly a union job. The people doing the actual shoplifting are variously unhoused, mentally ill, substance dependent, and desperate. It kind of depresses me how people think it's Kurt Russell with an eye patch stealing Ensure from Walgreens.

It makes the emotional aspect of the public defender more palatable in certain cases if he imagines his clients might depend on shoplifting out of absolute necessity a bit more than may actually be the case.

I read this as a joke. Touché, you've scored a point on the public defender meme account.

In case someone reads this as sincere:

This type of cognitive dissonance is neither necessary nor allowed for a public defender. In the first instance the day-to-day reality of unjust governmental administration is so insane that, not only would nobody from outside believe it, but it becomes counterproductive to engage in rationalization fantasies like the parent describes. I don't need to concoct a reason to feel sorry for my client--there are too many obvious real ones. I also don't need to feel sorry for every client to do my job well.

In the second instance, I am actually confronted by evidence all the time in a high-stakes adversarial environment. My client is going to jail for stealing diapers. If he makes up a story that he's not reselling them on ebay and I believe that story, I'd better be sure that I'm not going to get some PayPal statements in discovery the night before trial.
