In the charged environment of 2017 it took only a few hours for a baseball diamond to be transformed from a peaceful practice field to a horrific crime scene and then to a vivid symbol of the tensions between the angry politics of our time and the better angels of the American people.
From US President Donald Trump to congressional leaders of both parties to ordinary citizens came calls for prayers for the victims of the shootings that left House Majority Whip Steve Scalise and four others wounded, praise for the Capitol Police officers who prevented an even worse tragedy and above all words of reconciliation and unity.
But barely on the edges of those remarks was the outbreak of another round of recriminations and a renewed debate about what has brought the country to such a point of division, what is to blame for what happened on that baseball field and what if anything can be done to lower temperatures for more than a few minutes.
The country has been in this place before, perhaps too many times after violence that has Americans shaken and insecure.
At those times, elected officials have reached across the aisle, embracing one another in friendship and unity. Ordinary citizens have rallied behind those leaders as one nation, vowing to put aside partisanship and recalling what it means to be an American.
After the terrorist attacks of September 11, 2001, Republican and Democratic lawmakers assembled on the East Front of the Capitol and sang God Bless America in a display of national unity and resolve.
Today, as the news of what had happened on the Republican practice field spread, Democrats preparing for tomorrow's congressional baseball game elsewhere stopped their practice to huddle in prayer for their Republican colleagues.
The President spoke as other presidents have done in times of tragedy or terrorism, saying, "We are strongest when we are unified and when we work for the common good."
House Speaker Paul Ryan called on his colleagues to set an example. "Show the world we are one House, the people's House, united in our humanity," he said. House Minority Leader Nancy Pelosi, implored her colleagues to make the baseball game an occasion "that will bring us together and not separate us further".
But with past as prologue, other voices and other emotions threatened to drown out the words of the nation's leaders. Six years ago, after the shootings that left then-representative Gabby Giffords badly wounded and six others dead, it was the political right that was on the defensive.
Those on the left charged that the incendiary rhetoric aimed at then-President Barack Obama and his supporters during his early years in office gave rise to a climate that made violence possible.
Today, it was the political left that became a target from some on the right. The suspected shooter, James Hodgkinson, who was killed at the scene, was a longtime critic of the Republicans and a particularly harsh critic of the President. His Facebook page included angry words aimed at the President. Some Republicans saw the shootings as evidence that the President's critics have crossed the line of decency in their opposition and fostered a climate that could produce what happened today.
Former House speaker Newt Gingrich, speaking on Fox News, decried what he called "an increasing hostility on the left," whether from comedians, from artists, from politicians or from ordinary citizens posting their views on social media.
"You've had a series of things that send signals that tell people it's okay to hate Trump. . .," he said. "And now we're supposed to rise above it?" He added, "Maybe this is a moment when everybody takes a step back, but there is no evidence of it."
Republican congressman Steve King, whose many past statements have inflamed the debate over illegal immigration, was near the Capitol when the shootings took place. He went to the baseball field to pray, he said, but while he was there delivered a political statement in addition to his prayers.
Without referring to the shooter, he said critics of the President have created a climate of hate that threatens the country. He pointed to the massive demonstrations in Washington and elsewhere the day after the Trump was inaugurated and protests that have continued since. "America has been divided and the centre of America is disappearing and the violence is appearing in the streets and it's coming from the left," he said.
No one condoned what happened, no matter whether the shootings were truly motivated by political views or the actions of a deranged person with a gun. Recently, comedian Kathy Griffin found no sympathisers even among Trump critics when she posed with a mask of a bloody, severed head of the President.
Today, when it was revealed that Hodgkinson had been a volunteer in the presidential campaign of Senator Bernie Sanders, the senator rushed to rebuke him. "Violence of any kind is unacceptable in our society and I condemn this action in the strongest possible terms," he said on the Senate floor.
Republican Congressman Rodney Davis, whose district cuts across central Illinois to the Mississippi River just above the suspected gunman's hometown of Belleville, was on the practice field when the shootings took place. Still wearing his baseball gear, he returned to the Capitol to use the platform that proximity to the shootings provided him.
Davis condemned what he called "political, rhetorical terrorism" practiced by both sides. He appealed passionately for everyone on all sides to step back and find a better way to thrash out and then resolve their differences. "Is this America's breaking point?" he asked on CNN. "It's my breaking point. We've got to end this."
That's the question that many will ask, as they have asked it before: is this a true breaking point? After 9/11, there was a period of genuine unity across the political spectrum. But within a year, America had snapped back to its more partisan divisions and from that point forward there has been no turning back.
The campaign of 2016, fought on the raw turf of race and national identity, pushed things even farther. The America of 2017 is more passionately, and some would say angrily, divided. The political debates operate with an all-or-nothing mind-set, with no real grounds for compromise. And all politics has become more personal.
The uneasy alliance of parties forming the government is on the verge of collapse.
