filibusters
The obstructive tactic used by senators to block legislation by debating it at length is known as a filibuster. This parliamentary procedure allows a senator to extend debate on a bill, effectively delaying or preventing a vote on the legislation. By speaking for extended periods, senators can leverage the filibuster to bring attention to specific issues or to stall measures they oppose. Ultimately, it requires a supermajority to overcome a filibuster and proceed to a vote.

Single senator can block legislation in the Senate via a filibuster - continuing the debate indefinitely. It requires a 3/5 majority to end a filibuster (60 votes in the current 100 senator US-Senate). When the bill came before the full Senate for debate on March 30, 1964, the "Southern Bloc" of 18 Democrat Senators invoked the filibuster to prevent a vote on it. After 54 days, a substitute bill was introduced. Eventually a cloture (vote to end debate) was passed and the substitute bill was passed by the Senate on June 19.

Black Block is not a group or an organization but more of a tactic. This tactic is used as a safety and security measure. They people involved all wear black suits that are similar. So if someone throws a brick per se, the authorities would not be able to easily identify the person.
Mostly offices, including Senators offices.
