There is no justification for violence, for hate, for attacks on men and women who put their lives on the line every day in service of our families and communities. We must not turn our backs on each other. We must not be indifferent to each other. We must all stand together to reject violence and strengthen our communities.
Hillary Clinton, Democratic presidential candidate

"Regardless of motive, the deaths of these three brave officers underscores the dangers that police... confront every single day," he said. "We as a nation have to be loud and clear that nothing justifies violence against police officers."
He also warned against inflammatory rhetoric as both political parties prepared to hold conventions this month. "We need to temper our words and open our hearts - all of us," he said.

CBS, CNN and NBC News are reporting the name of Baton Rouge gunman as Gavin Long, 29, of Kansas City, Missouri.
This has not been officially confirmed by police.
“The movement began as a call to end violence,” prominent Black Lives Matter activist DeRay Mckesson told the New York Times on Sunday. "That call remains."
Mr Mckesson was arrested earlier this month protesting over the death of Alton Sterling in Baton Rouge. Mr Mckesson was released several hours later after the charges against him and scores of other people were dropped.

The attack happened about a mile from the police station
Image source, APThe local sheriff's office and a witness have told local media that police were responding to a shooting already in progress, placing doubt on whether the officers were purposely targeted.
Police across the US have been on high alert after five Dallas police officers were killed during a protest. They were singled out because they were police. However, the motive for Sunday's shooting in Baton Rouge is unclear.
"It's my understanding that they [the officers] had responded to an initial shooting incident," Casey Rayborn Hicks, public affairs officer for the sheriff's office, told local TV station WAFB.
Witness Brady Vancel told WAFB that he saw what may have been gang members shooting at each other before police arrived.
Some had urged the governor to tighten gun rules at the Republican National Convention in Cleveland after three police officers were killed in Baton Rouge, Louisiana. Five police officers were killed a week earlier in Dallas, Texas.
The law in Ohio is that people can openly carry a gun if they have a permit.
Thousands of police officers will be providing security for the Republican National Convention this week.

Police in Louisiana said they have used a robot to check for explosives near the body of the suspect who was shot and killed.
A week earlier, Dallas Police used a similar robot to kill a gunman who had holed himself up in a multi-storey car park. Micah Johnson had shot and killed five police officers during a Black Lives Matter protest.
