I've been watching with interest - and not a little frustration - the recent evictions of Occupy protesters in the States, and how the possibility of federal involvement in the raids has been covered by the media.
You dig through the debate at your own peril by now, but here's what I've pinned down.
More than a dozen cities moved to evict Occupy protesters from their campgrounds earlier this month, all acting in the space of ten days and using similar tactics. Department of Homeland Security vehicles were spotted at a number of the evictions, including one in Portland.
Later Oakland Mayor Jean Quan revealed to the BBC that she participated in a conference call of 18 cities before the wave of crackdowns began. There was another set of conference calls headed up by the Police Executive Research Forum.
Rick Ellis, a reporter for the (somewhat dodgy) news aggregate site Examiner.com, said an unnamed Justice Department official told him on background that local police agencies had received tactical and planning advice from Homeland Security, the FBI and other federal police agencies.
