Angered by a lack of progress, some of the more radical anti-textbook protesters decided to shut down schools by force. On the night of October 9, 1974, dynamite was thrown through the windows of one elementary school. Another school was firebombed and dynamited. Two nights later, protesters threw Molotov cocktails into a school; another school was firebombed a few nights after that. Then, 15 sticks of dynamite were exploded near a gas meter at the board of education office just after a meeting had adjourned. No injuries resulted from any of these incidents, but the level of violence and destruction shook the community.
