Of course they do. They worked hard for it, too, and I'd bet if all the video was released, within a year the Agents, CIs and other contractors would be identified, if not by name, then by their actions as just that.
The event was pretty much orchestrated to finally get 'some dirt' on the Right, even if it had to be created and incited by false flag operatives and murderous cops.
It is a pity that a few folks tagged along like tourists on a tour, because that's who is sitting in cells in DC (whether they were in the building or not).
There's a reason why the Feds have been so selective in the video they've released showing what happened last year.
Between this...the completely FBI run "kidnapping" plot against the Michigan governor and whatever that "march" was back in November in DC...it's pretty obvious that the Government is staging these events to polarize their base against the vast majority of Americans that don't buy into their Marxist designs on the country.
They used to be a lot better at hiding what they were doing...now they aren't even trying...that or they don't care who knows.
