Here's an explanation of the event. Even into this morning, I still see nothing on the news wires about the arrests.

Ellen Davidson, talked to U.S. Desk about the event and said they are gathering at the in New York City because they want “to mark the fact that we are now entering the 12th year of war in Afghanistan and we would like to take this moment to remember all the fallen; from Vietnam war, and Afghanistan war and Iraq war, and all the wars we are currently engaged in”.

“When we say all the fallen we also mean the civilians fallen, the veterans suicide after they come home,” she said, “We also want to honor those who’ve been wounded and damaged by the war.”

As to why they have chosen this specific site, Davidson said, “we want to assert our right to assemble and make our protest known, and on this particular site, on May 1st, some veterans and some members of Occupy were arrested for staying after a closing time of 10 p.m.”

She believes the unusual closing time was enforced because the police wanted to “break” the gathering.
