it appears that the murderer, Jonathan Ross, was holding his phone camera and filming the entire murder.

Christchurch much?

BTW we have plenty video of everything, there really is no question. I recommend this 404media article.

He should be prosecuted for destroying evidence.

Edit: surprisingly, his video was released around the time I posted this.

...the murderer, Jonathan Ross, was holding his phone camera and filming the entire murder.

Is that confirmed somewhere? Just holding his phone with a camera app open isn't enough. ICE has an app that uses a photograph to supposedly tell whether or not someone is a citizen. If there is evidence he recorded the incident for any reason, then I would think that that would be clear evidence of premeditation.

Some key details from the phone footage.

1. It was a handheld phone cam, not a body cam. ICE has thousands of dollars in equipment, but is choosing not to equip body cams; which could have kept his hands free to protect himself. Handheld allows the footage to be far shakier, so he can emphasize the idea he was "struck".
2. The footage doesn't contain all of the gunshots. In high likelihood, it had to have been edited before posting, for this to be the case.

prediction: Lost in a phone upgrade.
