Def include JFPO and Pink Pistols. Maybe even highlight those organizations. They are a great way to show that firearm ownership isn't just for straight white males. Maybe also include Maj Toure and his work with Black Guns Matter.
Also, I always advise caution when talking about the police thing, especially if there are police in the audience. Most police officers are good and decent people and will do everything they can to protect you. Coming at it from the direction of "The police will generally do everything they can do help you, but if somethin happens and their are no units avaliable, or response time is delayed, and the person breaks in or harms you, the court have ruled you cannot sue the police."
Most of the cops that will be in attendance are up in ranks in a department who's chief is all in on Red Flag laws in a county that leads the state. These people are not supporters and it wouldn't bother me at all if they got their little feelings hurt.
