I recently did a legal observers training where I encountered a new term for me called snitch jacking. From what I understand it's like gossip saying "so and so is a snitch, I think, I'm pretty sure they talk to the police." Since then I have been reading up on security culture within activist circles. The basics are don't brag about past or upcoming direct actions, don't ask questions like "so when is the illegal act happening" or "who is involved in it". Stick to a need to know basis. If you don't need to know the answer don't ask. If you hear someone asking inappropriate questions inform them that they shouldn't be asking those questions. It can be a good opportunity to educate less experienced activists. If that behavior continues you can assume they are an infiltrator. I guess the only part that confuses me is how to handle the situation if you become convinced that a certain person is an informant. I would think that you would want to inform your fellow activists that that person is not to be trusted. But I can see it becoming a slippery slope of needless gossiping. Your thoughts are very much appreciated.
