>> The worst mass attack on the nation's police since 9 11 at a Dallas protest already reshaping the 2016 race for the White House. I'm Andy Sullivan in Washington, where the killing of five police officers by a gunmen during an otherwise peaceful Black Lives Matter rally quickly bringing the campaigns to a screeching halt.
Donald Trump and Hillary Clinton tweeting out condolences and scrapping plans for campaign rallies in Florida and Pennsylvania.>> A brutal attack on our police force is an attack on our country.>> Clinton opting for a low key event at a Philadelphia church.>> Gun violence is ripping apart people's lives.
>> It's a sign of a sensitivity in political risks surrounding issues of police, gun violence and race. Donald Trump already getting a taste of that, his tweet, mourning the slain police and two black men killed by police in recent days, Trump preferred that those deaths it's senseless. That provoking blow back on twitter from people who wondered how Trump could use that word before all the facts are known.
On twitting, I thought Trump supported Law Enforcement. Even with the focus on the issue on the wake of Ferguson in a Baltimore riots last year, a new Washington Post study finds the killing of blacks by police continuing on the rise in 2016. Neither Trump nor Clinton can afford to underplay their support for police, but both also wary of alienating black and hispanic voters ahead of the election.
And at least for now, the tragedy in Dallas is replacing talk of Clinton's email investigation and Trump's questionable antics. All of this as both parties gearing up for their national conventions in coming weeks. Republicans who have long expected protests by Black Lives Matter confirming to Reuters that they have stepped security around their Convention site
