No arrests were made, but tempers boiled and ``Shut ups!'' were shouted inside the Blumer Community Room with its standing-room only crowd.
The audience nearly got hostile when David Pierce of Arlington brought up the Sept. 11 commission and the whether the Twin Towers were taken down in attacks ``perpetuated by government.''
He called for an impartial independent criminal investigation into 9/11 as audience members cheered.
Markey, a veteran congressman who represents Framingham, Natick and part of Wayland, said it's ``incontrovertibly true'' the terrorist-piloted planes caused the attacks.
``I do not believe President Bush participated in any conspiracy to bring down those towers,'' he said.
Some in the audience loudly shot back, ``That's a lie'' and ``Not true.''
A few argued with each other, shouting back and forth, ``Shut up!''
Officials called police as a Malden man, Phil Troudman, passionately argued in support of a conspiracy theory of controlled demolition that lays blame squarely on Bush's administration.
``I'm willing to go and take another look at it,'' Markey conceded.
The war in Iraq and impeachment for Bush and Vice President Dick Cheney were other hot-button issues of the day.
``It is unfathomable to me why we will not start impeachment,'' said Carol Coakley of Millis, who works at Framingham State College. ``If we don't do this, we'll lose our chance to restore our reputation in the world.''
Bush, ``who still has a `My way or the highway' sign on his desk,'' has written a blank check for war spending while the national economy spirals, Markey admitted.
During an eight-year reign, the president has overseen a ``sick care system, not a health care system,'' made the No Child Left Behind Act ``No School Left Standing,'' and ``demoralized'' the Republican Party, the congressman said.
But the focus now should be on electing a Democratic president - either Sen. Hillary Clinton or Sen. Barack Obama - who will take oath next January and ``on 95 percent of the issues, there's going to be a change,'' Markey argued.
The congressman said he supports censuring over impeachment because the proceedings would ``pretty much shut down the Congress from any business'' and therefore be the wrong course of action.
Members of the audience - still jumping to have their questions fielded three hours after the session started - groaned loudly when the forum was cut short at 3:30 p.m. on Super Bowl Sunday so the room could be cleaned.
``The custodians were only paid to stay until 2,'' Selectman John Stasik explained. ``It's going to cut into their game time.''
Constituents asked about everything from Bush's economic stimulus package to hydrogen energy to ``think globally, act locally.''
Larry Herson, commander of MetroWest's chapter of Jewish War Veterans, asked about Framingham being ``under siege'' with SMOC's lawsuit against the town on the table and whether the congressman could help with negotiations.
``It's almost a classically local issue,'' Markey said. ``It is not Washington to tell Framingham how to resolve this issue. It's very complex.''
``I saw a lot of passion in the people, I saw a lot of discussion - it was an exciting group,'' Westborough's Kate Donaghue, a member of the Massachusetts Democratic Party, said at the forum's end. ``It's exciting that so many people want to take part in the democratic process.''
