Yeah, I did too
Slashdot cracks me up
"Beware the surveillance state!"
"Give all cops cameras!"
As for the poll topic, I voted "It's not needed" because it was the closest to "It's not always needed all the time". Specifically, it's generally only needed when officers are interacting with the public (which is a lot of the time, but not 100%). Supposedly the Ferguson police chief had ordered body cameras, but they hadn't been deployed yet (that article cites unnamed sources, so the info is questionable).
But there are many times when cameras can help, both in protecting citizens from abuse, and protecting cops from false claims of abuse, and this is more important in some areas than others.
