Chokehold is an illegal maneuver, but headlock is an authorized move. Now, I don't know the first thing about the differences between the two other than whether it is allowed or not. However, I suspect the grand jury learned about them in detail and then some more. You should talk to those who actually sat through the grand jury process rather than making a call based on a partial video, or some politicians who want their five minutes' fame. Also, the federal investigation is ongoing. We should have some faith in the system. don't slam the grand jury. They are only humans.
On the other hand, I agree with you that the grand jury would have been more likely to indict him on a lesser charge.
