"Then the snatch-and-grabs started, targeting very specific individuals inside the police bubble. A large team of police and FIT officers would enter the cordon, target the individual, make a grab and drag them out whilst the surrounding police pushed back anyone trying to interfere with the operation. This tactic worked at least three times. Then a group of protestors attempted to block the grabs by linking arms and surrounding the next suspected target. This would have worked. But with the police capable of turning to physical force and violence at any time, and get away with it - any protestor acting in a similar manner would be immediately arrested for assault - the advantage clearly went to the yellow-coats."
