A Quinnipiac University poll released on Monday found broad support for Occupy Wall Street; 72 percent of New York City voters, including 52 percent of Republicans, said the protesters should be able to stay as long as they wanted if they continued to obey the laws. The telephone survey, of 1,068 registered voters, was conducted from Thursday to Sunday.

Also on Monday, Manhattan prosecutors met with lawyers for the hundreds of people who have been arrested during Occupy Wall Street protests, as well as with a woman who was pepper-sprayed by a police officer during a march.

The lawyers representing many of those who were arrested said they had asked prosecutors to dismiss the charges against anyone rounded up during mass arrests on the Brooklyn Bridge and at other demonstrations related to Occupy Wall Street. Martin R. Stolar, one of the protesters’ lawyers, said there was not enough evidence to prove the charges, most of which were for minor violations like disorderly conduct.

Even if prosecutors offer defendants what is known as an adjournment in contemplation of dismissal — a deal in which the charges are eventually dismissed if the person goes a certain period of time without being rearrested — Mr. Stolar said that “a substantial number of people” would decline the deal and “insist on going to trial and establishing their innocence.”

Erin M. Duggan, the spokeswoman for the Manhattan district attorney’s office, said in a statement that every arrest that comes into the district attorney’s office “is assessed individually, and charging decisions are based on the evidence and circumstances unique to each case and defendant.”
