That's a crapshoot. Either they will get the local media to care about it for a day or two, then fizzle, or they will get the local pizza place really pissed off, or someone will do something drastic and a bunch more arrests will start being made.
Getting 4chan to apply the right amount of pressure to the right place seems to be like trying to get an apathetic redneck to remove a tree stump for you. Chances are he's either going to whack it a few times with an axe and declare it unmovable, or blow it up. (To be fair, blowing it up works great, but can get people in trouble rather easily)
