alt Hacker NewsBoo! Don't blame the audience!
> Then Ulbricht walked into the public library and sat down at the table directly in front of me, and suddenly as I was reading I could look up and see exactly the chair he had been in, where the plainclothes police had positioned themselves, how they had arranged a distraction.
Alternately:
> Ulbricht had walked into the public library
gives the game away.
If you still want to play around a bit:
> I could see where Ulbricht walked into the public library. The table he sat at. I looked up and saw where the plainclothes police had positioned themselves, how they had arranged a distraction.
That way you are leaving some ambiguity, but are not directly lying with the tenses.
Well, a lot of times the audience is to blame... There are many people that are stupid, aren't trained in style figures of writing or just not trained in reading in a way that allows for complex conceptual frameworks. It also happens in software: someone writes great code, it's very complex and some people don't understand it and blame the author of writing unreadable code. Its easy to call something unreadable if you don't understand what it's saying. Let me bring it differently: it takes two to tango. I found his story interesting and engaging. Let me bring it in another way: Sometimes the joke is brilliant, but the audience just doesn't understand it. It's not a bad joke or a bad comedian. It's a bad audience.
To go into the meat of this: he is imagining it while reading in the same location as the incident happened. This is a style of writing. It's definitely not wrong.
