The basic rule is: even if the dispute becomes more heated: stay non-violent! Despite the massive worries at the moment: stay calm and relaxed. Take care of yourself. Then it is also easier to worry about others. And if you witness violence in the neighbourhood: Don't look away. Work for the weaker members of society. Right now we all have to stick together.
