This man did not need to die

After watching the video it's fairly apparent that Robert Dziekanski did not need to die. The taser was applied almost as a matter of convenience. The cops in the video appear fairly cavalier.

This is tough for me to say, because all the cops I know really seem to be doing a tough job for the right reasons, and it frustrates me that my profession (teaching) is often tarred with a big brush, but there are some sick people who work their way into policing. Let's face it, if you get a sick kick out of violence, policing is a great state-sanctioned way to live that out. It's too early to apply that sort of characterization here, but we need to have our eyes open.
