If you were to tell a police office you were about to go into a crowded square of people rioting against a city government and announce your intention to pay one million dollars to whoever shoots the mayor first, how should that officer respond?

Should he submit a request to have the case reviewed to the DA and ask a judge to allow him to stop you from taking that option?

The courts cannot be expected to individually guide every action (although law enforcement should be cognizant of the types of speech previously ruled to be free or restricted and respect that ruling with penalties for knowingly violating that precedent).

This stuff is complicated and making blanket statements is just silly. _Most_ speech should be protected, but some speech is limited.
