The classic star wars question - is Luke Skywalker a rebel hero, or a terrorist threat to order? Before the Empire blew up an entire planet to make a point, it was a fairly valid question.
It turns out, Americans pay attention when you start smashing property and taking flatscreen TVs.
It also demonstrates that by and large, police don't prevent chaos and property damage. Most of the time, people simply decide not to do this, and when they decide they want to, police are largely powerless to stop them.

Given episodes 7-9, Luke is a terroristic threat to order. After destroying the existing order, he failed to establish anything better and it quickly devolved into what we see in 7.
