There are people who will incite you. There are people who will kill you. There are people who might get you killed. There are people who will kill you and blame you for getting in the way of the bullet. There are people who will use the death of you and your fellow protesters for their ends. There are also those who will use your successes to their ends. People of powerful institutions will twist your failures and losses as well as your successes into their gains. These people might represent corporations, governments, and let's be frank, religious organizations. Be wary of institutions of all sorts reaching for and even spawning a group's successes or failures.
There are those in the protesting group who might act on the behest of an outside institution as well, sometimes merely for some silver. Sometime agent provocateurs will act to hurt authorities so that they can then retaliate "in self defense." And sometimes the authorities just don't give a damn and hire gangsters or outsiders to harm, maim, and kill depending on the threat to some damned oligarchic fashioning the protesters threaten. Protests stop situations to gather attention and when things stop the damned oligarchic fashioning ceases to grind and money ceases to flow. Protesting stops and gathers attention, the very point, and also threatens wallets. And there are those who will stop and nothing when their wallets and moreover their power is threatened.
Remember that despite the intricacies of the situation and despite the information presented the individual is always more important than the institution. There are people who will try to say that some institution is more important than an individual or a number of individuals, but no institution lives, no institution makes people, but people make institutions. The individual being stepped on and ridden must stand up and shake off those institutions riding his or her back. It is and always has been this way with individuals among institutions.
Remember that there will be people flipping and twisting information and acts and trying to manipulate situations for their ends. But the power is in the people's hands to bypass or surpass institutional influences and concentrate on individual liberty. Research all that you can about prior such rebellion. The eight hour workday in the U.S.A. was brought about by protests culminating on May 1, 1886 where 400,000 gathered in Chicago.
Police ultimately attacked the orderly protesters and a bomb was exploded. Though to this day it is speculated who threw the bomb, four people were hanged for the act. Others were later pardoned after doing time. Not only is their speculation as to who threw the bomb, but the judge was biased and the jury was rigged, as the story goes. The authorities cracked down expecting to eliminate the notion of an eight hour work day. Ultimately the U.S.A. got their eight hour work day. Research the May Day Haymarket Square, what led up to it and what happened after. Though the scale may be different and the storyline changed somewhat, at essence it contains the entirety of what one may face. Remember it is possible you are being manipulated, but it is possible for you to take control.
"If you think that by hanging us you can stamp out the labor movement... the movement from which the downtrodden millions, the millions who toil in misery and want, expect salvation - if this is your opinion, then hang us! Here you will tread on a spark, but there and there, behind you - and in front of you, and everywhere, flames blaze up. It is a subterranean fire. You cannot put it out".
