Account From Activist Kenneth Nichols O'Keefe

Here's the video:

The two key take-aways here are that:

1) They had complete control over the commandos, and did not harm them. As we see from the IHH pictures, they actually treated their wounds; and

2) they had taken away some of the commandos' weapons, but did not necessarily fire back; O'Keefe took two weapons and simply removed the (live) ammunition before discarding the weapons and ammo.  This fits other accounts stating that the activists did wrest the weapons away from the commandos, but did not use those weapons against the commandos.

(Oh, and taking all his stuff? Classy. Real classy.)
