Do I Interpret it correctly ?

-James: I have been arrested for murder! I am sitting here in jail How the heck did I get in this situation?
-Lawyer: Well, you shot your business partner. Then you wiped your fingerprints off the gun and put the gun in his hand so that it would look like suicide. Then you phoned your wife to tell her that you were going to say you had been with her all afternoon and that you wanted her to confirm your story if necessary. Then you went through the through your partner's pockets and took his wallet. Unfortunately, security cameras in your office caught the whole thing.

Lawyer whole dialog is in past simple because he is telling about the past action (emphesizing it), showing him why the present situation is really bad.

About James. I can understand the first sentence that he uses present prefect. It's all about that present situation is really bad that he was arrested and he is still in this situation, emphesizing the present situation, mentioning the past action. But how about the next sentence? "How the heck did I get in this situation?" past simple ? Is it some kind of emphesize to ? The past action of getting in this place, but more properly should be using here present perfect (present situation).

Oh and guys I know it might be rude from me but here is a link :

They are all time using past simple, while everything around is telling about present situation like : "We made this" so it's now here but they used past simple. Like well I don't get it.
