1:03 PM PT:  As pointed out by some in comments, its no surprise that federal law enforcement is involved with monitoring.
 In Hawaii:

FBI Watching Potentially Violent APEC Protesters

Honolulu Civil Beat - Chad Blair - 6 days ago
Montoya said authorities would protect lawful First Amendment protest, and that the protests won't be monitored or investigated.

"I think one of the very first things that we are very careful to do is that we are very careful to protect the First Amendment rights of every person on this island, every American, to be able to express their opinions, to protest freely without having to worry about someone watching," he said.

Monotoya continued:

    "At the same time, as we've seen around the world in some of these demonstrations, there are individuals that want to cause trouble, that want to break the law. And so, the interagency effort, essentially, is to identify those individuals and try to (prevent) them from destruction of property, or worse, hurting people. And that's an ongoing process."

Thus far, local protests associated with APEC have been peaceful.

Thirty people were arrested over the past few days -- eight at an Occupy Honolulu event on Saturday targeting APEC, and 22 at a Hawaiian sovereignty protest at Iolani Palace on Monday. Another Occupy Honolulu protest -- at the Hawaii Convention Center -- was set for Tuesday afternoon.

Monitoring is one thing.  What will be news is if it is soundly sourced that FLE lead or coordinated the removal of Occupy camps imo.
