Dash cam video shows a car appear to lose control and swipe a police officer on Interstate 95 in Palm Beach County, Florida.

What I found most interesting about the first video (which isn't much) is that apparently a LiveLeak member works in the video editing room at HLN: No aftermath permitted, and replay loops until nausea occurs.

The second video is from the WPTV original source, which shows more of the video with better information.
