Today's edition of quick hits:
* The latest from Dallas: "A suspect in the ambush of 12 Dallas police officers 'wanted to kill white people, especially white officers,' and was upset about recent police shootings, the city police chief said Friday. Dallas police on Friday identified the suspect, who they killed in the early hours of Friday morning, as Micah Johnson, 25."
* Micah Xavier Johnson: "The man identified by a senior law enforcement official as the sniper who shot a dozen Dallas police officers, killing five, served in the Army Reserves for six years and did a stint in Afghanistan, officials confirmed Friday."
* Aftermath: "Police departments across the country stepped up security and took other precautionary measures in the aftermath of Thursday night's shooting at a protest in Dallas that left five officers dead and seven wounded."
* President Obama ordered flags be flown at half-staff "as a mark of respect for the victims of the attack on police officers perpetrated on Thursday."
* Johnson was killed by a robot carrying an explosive: "The move represents a potentially unprecedented use of robots to deliberately deliver lethal force in domestic policing, according to experts, raising questions about how local law enforcement officials are deploying the high-tech tools that increasingly fill their arsenals."
* Iraq: "Militants fired mortars on a Shiite shrine north of Baghdad late on Thursday, and in the confusion that followed, three suicide bombers in military uniforms infiltrated the compound and blew themselves up, the Iraqi authorities said. At least 36 people were killed and more than 40 were wounded."
* Bizarre GOP priorities: "Nebraska, joined by nine other states, filed a federal lawsuit on Friday seeking to halt implementation and enforcement of the Obama administration's policies providing transgender protections under current law."
* The hottest June on record: "The month's average temperature in the Lower 48 states was 71.8 degrees, 3.3 degrees above normal, surpassing the Dust Bowl record set in 1933 by a couple tenths of a degree, the National Oceanic and Atmospheric Administration reported Thursday. Every state in the nation was warmer than normal in June, with Utah and Arizona having their hottest Junes."
* Drilling: "The Obama administration on Thursday finalized rules that will require companies to have strict safety and environmental protection plans in place before they drill for oil or natural gas in the Arctic Ocean. The new regulations do not expressly prohibit drilling in the Arctic, but they require companies to submit detailed plans for how they will drill safely and respond to oil spills and other emergencies."
* Sometimes, change happens fast: "Eight U.S. airlines will be awarded 20 direct daily flights between U.S. cities and Havana, with service to begin this fall, the Transportation Department announced Thursday."
* It's the last 13 words of this sentence that stand out: "Health officials in Arizona say the largest current measles outbreak in the United States is in part because some workers at a federal immigration detention center refuse to get vaccinated."
