Tactics used by the US media to discredit protesters as outlined in Inventing Reality: The Politics of the Mass Media by Michael Parenti.

1) Scanting of Content: "the event is depicted as something of a spectacle connected to little more than its own surface appearances"

2) Trivialisation: "By directing our attention to surface appearances and ignoring the substance of the protest, the press is free to ascribe irrational and frivolous motives to the demonstrators"

3) Marginalization: "The protesters are portrayed as a deviant and unrepresentative sample of the American people...Another way to marginalize a group is to portray it as violent and irrational, or linked to groups thought to be violent, or in some way threatening and disloyal"

4) False Balance: "Under the guise of evenhandedness and objectivity, the press will give disproportionate attention to counterdemonstrations and unsympathetic authorities"

5) Undercounting: "Another way to discredit demonstrations is by undercounting the protesters...Conversely, right-wing counterdemonstrators are overcounted, thus enhancing their legitimacy and diminishing the effect of the larger protest"

6) Omission: Perhaps the most common...form of distortion is nonreporting...most media stories about protest, as with coverage of strikes, simply omit what the struggle is about. The reader or viewer is left again with the question: "Why are these people behaving this way?"
