Katie blogged this episode yesterday, in which President Obama made an active decision not only to politicize the funeral of five slain police officers with a strident gun control message, but to do so with the cartoonishly false claim that handguns are more readily available to teenagers than computers or books. It would be a challenge to improve upon Charles Cooke's instant reaction post at NRO -- but I'll at least endeavor to add to it in a moment.

Without mentioning Trump’s name, the former president preached tolerance and civility at a memorial service for slain officers in Dallas. Everyone knew who he was talking about.

Shootings of police and black men have highlighted the uneasy intersection of race and law enforcement. But in Dallas Tuesday, both Presidents Obama and Bush will stand together.

President Barack Obama is traveling to Texas Tuesday to pay tribute to the police officers killed by a sniper last week. Obama will be joined by President George W. Bush at an interfaith memorial service in Dallas at the Morton H. Meyerson Symphony Center.

As gunshots ring out around her, Vickie Kale shakes her head in disbelief.

“How can you point your gun at someone and shoot them?” asks the certified firearms instructor. “What can make someone so mad they would do that?”

Kale runs Gibson’s Outpost & Shooting Range, barely a mile from where police say Micah Xavier Johnson lived before he attacked Dallas police Thursday night, killing five officers. Gibson’s is the closest range to Johnson’s home, but no one here recognizes him or remembers him. If he practiced, and they say he must have, he practiced elsewhere.

Following the deadly police ambush in Dallas Thursday night, one spokeswoman for Hillary Clinton blasted the media for circulating an “inflammatory” photo of the accused gunman.

It was midmorning in the Capitol on Friday, with five police officers dead in Dallas and two young black men dead in Louisiana and Minnesota, when an anguished House Speaker Paul Ryan strode onto the House floor.

President Barack Obama called the fatal shootings of several Dallas police officers “despicable,” and said that it highlighted the need for better gun control laws.

“There has been a vicious, despicable, and calculated attack on law enforcement,” he said. “Police were doing their jobs, keeping people safe during a protest.”

The president said the shooting highlights the need for a new debate on gun control laws.

The ambush that left five police officers dead at a protest in Dallas on Thursday has altered the contours of the presidential campaign, with Hillary Clinton and Donald J. Trump canceling political events on Friday and striking different tones about the killings.
