Due to technical difficulties, full video is not being posted.

These images show fairly well that a demonstrator was
pushed into the police line by someone clad in black, with a
hoodie and mask, who then walked *through* the police
line and up the stairs to hide on someone's front steps
behind a tree.

The arrest occurred just as another arrest was executed.
Some felt the first arrest -- which appeared to be orchestrated as
if to look like police lines were attacked -- was a
distraction in order to execute the second arrest.

When one videographer tried to position himself to
get an image of the hiding saboteur, police charged him.

When people demanded to know who the saboteur was, and even
demanded that he be arrested (citizen's arrest, which the
police have the duty to execute), he left the steps and walked offthrough
many more police officers.

Many thought this was clearly a police set-up.
That may not be the case, but there is little question
that the saboteur was working with police, and
probably was a police officer.
