This is on point. I'm Begna Chakrabardi. The Special Memphis Police Unit involved in the

beating death of Tyree Nichols has now been disbanded. But similar units exist in other

American cities. Lawmakers and law enforcement leadership say the units are especially important

to suppress crime in victimized neighborhoods. Is that true? Are they effective? And how often

are these specialized police units involved in cases of egregious police violence? Well,

Seth Stoten was once a patrolman on the Tallahassee Florida police force. Today he's a professor

of law and criminology at the University of South Carolina. He has studied the body cam

I made or assisted with literally hundreds of arrests used force on a number of occasions against

individuals who were trying to get away or otherwise. And I never saw anything like this from

my colleagues. Stoten describes some of what shocked him most as a former police officer.

closed fists while he's on the ground. You see them apparently holding Mr. Nichols while

another officer strikes him in the head with what is at least at times a closed fist. You see

officers holding Mr. Nichols on the ground while another officer kicks him. You see officers using

for officers to say that they were afraid that Mr. Nichols was going to hurt them. Early on in

the videos, you see an officer opening his driver's side door and physically reaching in and pulling

Mr. Nichols out. That's a really bad idea on a pure tactical level. For an officer to reach into
