President Obama, in remarks at the beginning of his health care town hall, spoke directly to those who might try to disrupt the event.
"I do hope we will talk with each other and not over each other," he said to applause. "Where we do disagree, let's disagree over things that are real, not wild misrepresentations" of what's in the bill.
He also deplored the "scare tactics" and "boogeymen" employed by the opponents of health care reform.
"For all the scare tactics," he said, "what is truly scary, what is truly risky, is if we let this moment pass."
