Scrub the video back and forth around that time and you can see an object in his left hand, which is likely the knife they found on the floor of the car he was trying to enter. If they ever release photo of the knife I will lay odds it has a curved blade like the example in the image.
Check the 46 second mark of the video at the top of this page:

I am glad that these officers have seen 'Surviving Edged Weapons'.
