As LaSexta has revealed, the Democratic Tsunami plan did not go well thanks to the Security Forces.
First they prevented about 100 people from entering the field as attempted at gate number 18 of the stadium before the break. 30 managed to enter and then were repressed. According to LaSexta, the plan had several steps and one of them was to cut off the electricity supply and that the markers were not seen, but the Mossos avoided it by reinforcing security.
It was also intended to display a giant banner, but the Mosso requisitioned it and there were drones prepared with vindictive messages, but neither could they carry it out.
