While I think the Ferguson protestors - the violent ones, anyway - should have been given a full blown Jin Roh Wolf Brigade style beatdown, I admit that the proposed solution of 'every cop has to wear a body camera' is one I favor entirely. Police officers having their every interaction recorded will help weed out corruption, and likewise weed out inane 'gentle giant' claims.
In fact, in my view - this plan doesn't go nearly far enough. I would like to see cameras mounted on every public servant in the US.
Every defense attorney.
Every professor at a public university.
Record them all, I say. In fact, make it illegal for them to correspond about matters of the public interest without live-stream feeds going out over the internet and being permanently recorded on publicly accessible hard drives.
I believe in a right to privacy for private citizens. But not for politicians, or public servants - at least in their official capacities.
You may think I'm trying to make a point here by advocating something that sounds ridiculously extreme. If so, you're wrong - I don't think this is extreme at all.
