Detroit police chief: Officer's death should be "tipping point"

• White said Thursday he believes Davis wanted to "commit suicide by cop."

The latest: The courts and politicians need to "step up" instead of just saying they plan to do something about violent crime and guns, White said in a press conference.

• "This is unacceptable and this should be the line. Whatever your tipping point is, this should be it," he said.

Details: It's unclear whether the assault-style gun police say Davis used, a Draco, was purchased legally. But White spoke incredulously about why that type of weapon is even available to buy at all.

• White also decried potentially lenient treatment for suspects with violent histories.

What they're saying: "I write this not for you to say I'm so sorry but because this man was so much more than a police officer," Courts' wife, Kristine, wrote in a Facebook post cited by the Free Press.

• "He was an amazing dad, my best friend and the man I married."

The bottom line: "I don't have the words to make (his family) feel better. All I can do is promise them we'll never forget him," White said.
