The nation's largest financial institutions are preparing for the upcoming Occupy Wall Street's May 1st demonstrations by communicating with police, according to The San Francisco Chronicle.

Brian McNary, director of global risk at Pinkerton Consulting & Investigations, said that banks from America and overseas are working together to "identify, map and track" protesters across social networks in order for business meetings to avoid disruption.

Demonstrations in 115 cities are being planned for this coming Tuesday, inspired by the 1886 Chicago's Haymarket Square clash between police and workers.
