Semicontrolled Demolition

Image text: I believe the truth always lies halfway between the most extreme claims.
This comic is taking the idea of a compromise to its literal extreme.
9/11 Truthers are people that consider the conspiracy theories around the September 11th 2001 terrorist attack and they usually believe that the destruction of the World Trade Center in New York City was an inside job by the government.
So, this comic is a compromise between what the truthers believe and public knowledge of September 11th and since the comic takes the compromise to its extreme, in which both things happen.
Bag Check

Image text: A laptop battery contains roughly the stored energy of a hand grenade, and if shorted it ... hey! You can't arrest me if I prove your rules inconsistent!
It's never a good idea to mention what possibly dangerous stuff you have in your bag at the airport. Probably better off just buying a new water after the check point. No matter the inconsitency of the rules. And the joke in the image text is that you can very easily be arrested on inconsistent rules.
