Dogging Rudy along the parade route were at least two anti-abortion protesters. One carried a sign that read, RUDY GIULIANI DEMOCRAT IN DRAG. Another one, wearing a t-shirt that read ABORTION KILLS BABIES, walked through the crowd shouting vicious anti-Rudy messages through a bullhorn: "Rudy Giuliani is a Democrat who wants to continue the wholesale slaughter of human beings and make you pay for it! If you are a Christian you cannot vote for the murder of innocent human beings. The blood will be on your hands."Although some in the crowd were shooing him away, many dozens of people definitely heard the message loud and clear.
Contrary to what you say, your picture has Rudy about to speak from a podium before he was interrupted.
