President Obama meets with police chiefs in the white house,explains the reason for the problems America faced last week

President Obama yesterday met with police chiefs,community advocates and elected officials at the Whitehouse to discuss ways to stop the re-occurance of the problems America faced last week where black people were brutally murdered and some police cops lost their life's too in revenge.
President Obama while discussing with them said,

"The roots of the problems we saw this week date back not just decades, date back centuries. There are cultural issues, and there are issues of race in this country, and poverty, and a whole range of problems that will not be solved overnight. But what we can do is to set up the kinds of respectful conversations that we've had here—not just in Washington, but around the country—so that we institutionalize a process of continually getting better, and holding ourselves accountable, and holding ourselves responsible for getting better."
