I am personally offended by the frequent picketing of the private homes of public figures (Senator Feinstein and Congresswoman Pelosi are constantly picketed at their homes).
I am an activist and I can say it would be costly to protect myself from such tactics and very intimidating to me, friends and family.
This tactic was originally endorsed and promoted by Saul Alinsky, idol of Barack Obama (an intimate friend of my mother's).I believe it is not protected by the First Amendment. The most recent case on this issue was Virginia v. Black et all, a cross burning case.
The U.S. Supreme Court found that "a state, consistent with the First Amendment, may ban cross burning carried out with the attempt to intimidate." In so doing, the Court created a new area of constitutionally unprotected speech for "true threats." Under that carve-out, "a State may choose to prohibit only those forms of intimidation that are most likely to inspire fear of bodily harm."
Those words describe pickets in front of a private home to me. I rest my case. Lets get our states to ban political picketing in front of private homes.
