I've uploaded a copy of the football cop tackling a cyclist video to portland.indymedia.org , see the link below.

how to watch:
You can play this even if you have a slow modem. Download the video over a slow connection, then get the VLC video player for mac, windows or linux. The video on youtube was choppy. This video I've uploaded works great.

How to download videos from youtube:
You can pull videos off youtube under fair use copyright laws. The tools you need are simple, get firefox and the plugin called video download helper. Then you will see a blue and red icon at the top of your screen. Click that to pull a video down from the internet.
