the whole article is bizarrely based for a local news crew
No one believes that.
People believe, based on a lot of good evidence, that Chris can't shut the fuck up- and that's all it takes. Not some dramatic showdown with a cop slamming a phone book down on a table or a 'lady cop' bringing tendies (although it is entirely possible that they offered him something to drink\eat). He probably started yapping unprompted in the back of the car. He was already saying weird shit before they got him in there.
After booking, some non-uniformed cops would ask him to sit down in an interview room, take the handcuffs off if they weren't already off, probably mirandize him again just in case, and then talk. Some people who hate the cops really will refuse to say a word, even if they've been shot and the cops are asking who did it. Chris is not such a person. How many times did he keep talking to trolls even after it was absolutely clear they were fucking with him? How may times did he tell them
self-incriminating information even though they didn't even ask (sometimes in an effort to cover other things up that were much less embarrassing)?
This is the guy who just wrote a letter to someone (Marvin? idk) completely incriminating himself and had him pass it to Null, who he says had betrayed him.
He cannot help himself.
