Protesters take the mic at Wisconsin police shooting press conference

A day after an officer shot and killed a man in Madison, Wisconsin, police say the man had fled from officers, then pulled a fixed-blade knife, injuring one officer, who tried a taser before firing three shots. Protests developed almost immediately, and on Thursday, demonstrators took the microphone in a police press conference. Jonah Kaplan reports.
