In this case, the alleged perps -- Onta Williams, James Cromitie, David Williams, and Laguerre Payen -- were losers, ex-cons, drug addicts. Al Qaeda they're not.

G20 police 'used undercover men to incite crowds'

A British Member of Parliament claims he saw two undercover cops acting as agents provocateurs at the G20 demonstrations, attempting to get the crowd to riot. It was during one of the "kettling" sessions (this is a tactic used by UK cops wherein all protesters and bystanders are crammed into a physical space that is cordoned off indefinitely, and though the protesters are not charged with any offense, they are not allowed to leave, seek medical care, use toilets, etc). The men apparently threw missiles at the cops and tried to get others to do the same, then, after being accused of being provocateurs, flashed credentials at the police and passed through their lines.
