Video reveals shockingly slow police response to Uvalde, Texas school shooting

Newly leaked surveillance footage from inside Robb Elementary School during the shooting in Uvalde, Texas seems to contradict what many gun advocates say is the best response to a shooting: a “good guy with a gun.” As Jackson Proskow reports, the footage shows heavily armed police officers standing in the hallways of the school as the shooting continued, ultimately killing 19 students and two teachers.
