"Lawful orders to disperse" is there such a thing? You don't hear about "lawful orders to stop speaking" or "lawful orders to stop practicing a religion "
And just because a" clear verbal warming " was issued, doesn't mean it had to be followed, nor does it mean excessive force woukd be used.
While I agree that some instances of "peaceful protestors" aren't actually peacful, many are. And in some of the cases where the protestors aren't peaceful, the show off force is exessive.
When your protest becomes a riot, yes, it is lawful to order dispersal. You have a right to expression, not a right to ransack other people's property (public and private), if you commit the latter in the guise of the former, then you are in the wrong.
