Any raid being apologized for by the PM has nothing to do with his previous exploits which he has already been indicted and prosecuted for.

Okay, so if he's been prosecuted for it and served his time, then he's fulfilled his debt to society, no?

It means "he's a self-made man" is a claim which needs to be shot down, and that's the claim that was being shot down.

How so? If he committed some crime, got convicted, did the time, then started a business and bootstrapped to success, how is that not a self-made man? A great many successful entrepreneurs (Branson comes immediately to mind) were criminals before they were successful.

Some people find it hard to understand that it's possible for an investigation to be mishandled and the person being investigated to still be a criminal.

No, because rule of law is important even when you're dealing with criminals.

I'm not quite sure of the point you're trying to make?
