A newly formed social protest group gathered Sunday afternoon to demand the Sheriff's Office cancel the planned appearance of a controversial police trainer. Lt. Col. Dave Grossman, a prominent law enforcement trainer whose philosophies are the subject of regular criticism, was set to host a “mindset bootcamp” event that included topics such as “combat preparation for your spouse and family,” active shooter situations and what makes a person a “winner,” according to a flyer for the event. Instead, he'll appear at a public forum, but protesters say he shouldn't be in Spokane at all.
