The outside agitator charge is one that has historically been invoked by authorities with bad arguments. Whatever misdeeds they have committed to provoke protest are indefensible, so they resort to canards. Usually the target is some sort of lefty agitation.
Any fool should know that an unimpeachable movement, for civil rights, was fueled by outside agitators, as well as inside ones. Civil rights workers came to the South from all over the U.S. to help register black people to vote. Union organizers often come into places they’ve never lived in before. So to suggest there is something inherently bad about outside agitators is usually reactionary bullcrap.
Of course it matters what sort of agitation is involved. Bad or unwise agitation is what it is, aside from its authors. When Al Sharpton was ranting about Korean grocers, that was inside agitation.
The other reactionary angle to outside agitator mongering is the implication that protest be confined to narrow subjects and goals. Politics is all about motivating big ideas by reference to specific incidents, among other things. So resistance to broadening protest is another form of reaction. I’m not on the ground in Ferguson, so I can’t say who is doing what to whom. All I can say is that justice for Michael Brown is a laudable objective, but it is not ambitious enough. What about the next Michael Brown? You know there will be one.
There are some visible outsiders in Ferguson who are very unlikely to make any sort of productive contribution. Making it easier for police to attack non-violent protesters by chucking shit, besides being cowardly, is a sure way to shut the whole thing down. On the other side, it’s possible that some local leaders would like to chill things out as much as possible, which means demobilize people. I don’t fault their intentions, but demobilization is not something to hope for.
There would be less downside to demobilization, which seems to be happening, in light of the evident lack of any organized action. If the only thing people are going to do is walk up and down the street saying justice for Michael Brown, they might as well go home. That message has been delivered. Absent any expansion of the protest, both thematically and politically, I’m not optimistic about the outcome.
