There's absolutely no way weens will let that happen, I bet attention seekers like Ethan Ralph might even be willing to camp out in their car around near 14 Branchland Court when Chris gets released for the opportunity to livestream Chris getting arrested again or film him trying to get back into his house.
I'd say that's because there was constant media refrences to Trump (
Even My Little Pony refrenced Trump) and the news kept referring to him like he was an over the top villian so it's easy for Chris to think 'Hmm yes, I will be part of getting the first woman elected over the big bad orange man!' (There's also the whole Lisa Simpson vs Trump thing too).
The only real reference to 9/11 would be either watching action films or seeing other terrorist events on the news and he'd probally think
'Mmyeah that's bad but anyway..' or something like that since like
@Phalanges Mycologist said it didn't have any immediate direct effect on him.
