In May of 2014, reports the Minneapolis Star-Tribune, Yanez underwent a 20-hour seminar on "Street Survival" taught by Illinois-based Calibre Press, which teaches courses on the subject to police officers nationwide. The company's "Street Survival Seminar" overview displays a monomaniacal focus on that most important of all policy considerations, "officer safety." It treats every police encounter as a combat situation in which only one life truly matters – that of the government's armed emissary, not that of the citizen who is supposedly being protected and served by him.

Although Calibre co-owner Jim Glennon has written that viewing "police as the enemy is not a healthy or helpful position for a society to take," the courses presented by his company relentlessly teach officers that the public is their enemy. As one instructor summarized the course for the benefit of his students,  "We've got to survive this job!"
