The reverse could be to say the activists like Amy Goodman are exploiting the 1st amendment to push their agenda. She isn't really a reporter. That said, the historical interpretations of the 1st amendment are very loose in this regard and this is definitely a bit of posturing to make other smaller activist style reporters afraid to report from within protests.

On the bright side, Amy Goodman has connections to take this to a higher court which would very likely set a stronger precedent for protecting camera phone temporary reporters and others who film events from the inside.
