Cops on camera

This blog post discusses the inevitable benefits of cops having cameras and being filmed - for their own protection.  IMHO it is NOT if but when.  The prices of suitable technology is falling and soon it will be difficult to ignore.  Certianly - from the comments below - it is hard to see why SWAT teams could not divert a little of the funds they spend on all the other toys to protect themselves from lawsuits (unless they would just increase).
