The tanks aren't positioned in an offensive manner. They
would not have been so close. I'm no military tactician,
but i don't see why two tanks would pull up along side a
protest, drivers out through the roof, and ask people to disburse.
Those 3 bicycle cops were more effective in containing
those protesters than the 2 armored tanks were.

It doesn't make sense. Though, I did find it odd that military
units, (especially those as slow moving and damaging to the road as tank tracks)
would be able to drive on public highways...
