Solidarity first: find a whole load of people to go with, otherwise your "take the risk to be attacked by security forces" is just "suicide by cop".
You cannot do this as a large number of independant individuals. You need an organisation, or several; and yes, that means politics and compromise and all the other things about working with people.
With other words, stop being afraid and take the risk to be attacked by security forces.
That is the only way.
