Reminder: do not sign up for rallys/protests, do not hit "interested" or "going" on Facebook events for protests or rally, leave your phone at home and buy a burner for emergencies, cover your face and any identifying marks. You do not want the police to be able to place you there in any capacity. The police are not your friend. At this point, they're your enemy.
They no longer have to read you your Miranda rights. If you are stopped or arrested by police, the most important thing you can do is ask for an attorney and stay quiet. You can memories your rights down below, but staying silent is also an option. Do not answer any questions, do not respond to them at all.
If you are going to a riskier event (i.e. more potential for police intervention) bring lots of water, and heat resistant gloves. There is a high chance they will throw tear gas at you. You can douse it with water or throw it away from the crowd with the gloves.
Do not engage any pro lifers you come across. The police are looking for any sign to engage. Do not yell at them, do not touch them, stay a good distance away.
Make sure at least one good friend/family member knows where you are and has the numbers for local jails and hospitals. Keep emergency contacts on you (but not visible).
