rightwing pissants, police cadet wannabes and neo-nazi skinheads who pose as anarchists and smash up stuff at protests in order to justify security crackdowns, roughly the same political agenda as the blackshirts and brownshirts of the 1930s.

If the black bloc weren't pissants, they'd do their thing on their own, rather than during peaceful demonstrations.
At summit conferences in Genoa, Pittsburgh, and Toronto, the 'black bloc' was abetted by police.

During the 2010 G20 Summit in Toronto Canada, the police claimed that they were working to stop attacks by the Black Bloc Anarchist group.
In doing so, the Police became the Blue bloc for illegally detaining over 200 citizens against there will while not under arrest.

The police in Riot gear would step forward, (identity hidden by helmets) target an individual with their clubs and shields. Then step back into formation thus making it very difficult to identify the specific office who assaulted the citizen.

Just like the black-bloc
Dude, Heads up, the blue bloc is locking up more protesters.

revolutionary anarchist street tactic where participants engage in direct action against the forces of corporate and state repression, dressing as the indigenous zapatista rebels of chiapas do, in black with bandannas or balaclavas. also the bane of bed-wetting conservatives, cry-baby liberals and ignorant neo-fascists alike, many of whom have been upstaged or bitch-slapped by the black bloc with extreme vigilance.
"The Black Bloc pissed all over George Bush's inaugural parade in January, 2001."

We were worried about random insurgent penetration from the rear of our area until Dick Kingerly turned us on to a new protection product called Cop Bloc. Now we feel much safer on Thursdays which had become the insurgents most probable day for what is now known as the back door pig bath.

during protests, the black bloc is the group of anarchists on their bikes wearing black hoodies with the hoods on, and a bandana over their face so only their eyes show. They are usually spotted heading off on breakaways and they do things like smash windows of corporations, refuse to obey police orders to disperse, and fight back during police brutality. However, they do not do this just for fun, or because they are bored. They have political agendas that no one agrees to accept or consider so they revert to agression to pique interests. They are also very much against the cops. Usually, Black blocs will erupt with their messages during critical political times (i.e. going to war with Iraq)
Here in San Francisco, the black blocs show up for just about every single protest, and they organize breakaways. However, they usually fail to incite any kind of rioting, save the one right after the first bomb was dropped in Iraq. Then, they shut down the financial distrct of this city, even though it had no affect.

What happened to the times when black blocs did REAL riots with and REAL damage???
