Police arresting people for video-taping them

Following is a comment I posted in response to an article by Jacob Sullum on The Patriot Post that appeared in The Evening Sun today under the title "Shielding officials from scrutiny" (click on this link to read the article on which I am commenting):

 We ignore this at our peril. When the Nazis began rounding up and executing Jews, they made it a crime to watch. If our government succeeds in preventing us from being able to “watch” them, it will inevitably lead to increased misconduct, atrocities, and the loss of freedom. Also, if I am unable to record incoming phone calls to my home, then my ability to defend myself and my family against all sorts of threats is greatly compromised. The requirement that I must obtain the permission of people who are calling to threaten, harass, scam, or molest me or my children prior to my being able to legally record them is absurd. Are the police going to set up a wire-tap sting operation at my house to protect me from these type of threats? I don't think so.
