See here and here and here and here for news coverage. The following is a first hand account
I attended.
From 8:30 am to 10:30 am, I was present at a mass Tefillah protest against this mass false messianic movement. Unlike these reports, I estimated that there were between 2000-3000 people there, and very few non-Shomer Shabbos people, if any. Maybe they came later. We all Davened on a large grassy area outside the Metro-West complex at the far end of which, and blocked by numerous police, was a building where the Meshumads and their friends were doing their Christian thing.
Chairs were provided and tables set up for Bimas, some Sefardi and Nusach Sfard ad hoc “Siddurim” which were printed just for the occasion by Yad L’Achim were available, although most people came prepared with their own Siddurs and Chumashim.
Due to the largeness of the crowd, and the desire of the Sephardim and the Yemenites to have their own Minyans, not to mention a large group that wanted to Daven with or close to the Clevelander Rebbe or one around Rabbi Peretz, the mass subdivided into some dozen or so Minyanim.
The biggest problem was that there were only a limited number of Sifrei Torah and so when it came to the layning, Minyanim united.
I did not see any violence whatsoever, however, later I heard of a boy who crossed the police lines, was arrested and then followed by his father who tried to save him and was also arrested, were both beat up and bloodied in the police van. There was only one Meshugener there who walked around for a couple of minutes yelling out “kill them” (in English, Davke) but he quickly disappeared.
The Davening was very peaceful, albeit it noisy at times when some of the multiple Minyanim would call out things like “Shma Yisroel” and similar key verses, just as a protest or those closer to the Meshumad building would scream with catcalls and boos. In a way it was very difficult to get any real Kavana because of the loud Sephardim and Yemenites, not to mention the outdoorsy, disorganized, circuslike atmosphere at such events. Fortunately, there were a few relatively normal Ashkenazi minyanim, too, where I ended up.
Towards the end of Mussaf, some people began setting up a minimum Kiddush with wine and rokalach, but I was already packed up and ready to leave.
I did not see or hear any anyone speak to the crowd or was there any attempt to get everyone to say Tehillim together or anything like that.
There are no overt signs of the media there and I only saw one person taking a photo with his cellphone. I did not see TV cameras or microphones.
For the most part, the protest went by unnoticed by the mainstream press.
Rachel was there, too, on the other side of a sheet-strung ad hoc Mechitza.
