It has been 10 days since a white police officer's shooting of an unarmed black teenager triggered emotional, expansive protests that have increasingly devolved into chaos and violence. Officials say "criminals" are hijacking the peaceful protests. Many demonstrators lay the blame on outsiders. But according to St. Louis County Police there's plenty of blame to go around.

Police tactics in Missouri aren't the only place they've come into question. Michael Bell was a 21-year-old white man who was shot and killed by police in Wisconsin.
His death ultimately changed the way police shootings are investigated.
CNN's Kyung Lah is OutFront with that story.
(CNN) - While protesters in Ferguson, Missouri are demanding justice for the killing of Michael Brown by police, questions are being asked about the man who at the moment is responsible for pursuing any prosecution and whether he can be impartial.
Some residents and community leaders contend St. Louis County Prosecuting Attorney Robert McCulloch has deep ties to the police and has favored law enforcement in criminal cases.
Missouri State Sen. Jamilah Nasheed launched a petition that now has more than 26,000 signatures to remove McCulloch from the case and replace him with a special prosecutor to handle any criminal case arising from the August 9 shooting of Brown, an African-American who was unarmed when killed by a white police officer.
The shooting has touched off demonstrations that have led to confrontations with police, and some looting and violence. The National Guard has been called in and President Barack Obama is calling for "understanding" and cooler heads.
Officials in Ferguson, Missouri are bracing for another night of violence as frustration mounts over the unarmed black teen shot and killed by police.
Protests continue to spiral out of control at least 74 people were arrested Monday night. Demonstrators hurled rocks, bottles, and molotov cocktails at police who used tear gas to disperse the crowds.
Four officers were injured and two protesters shot, though not by police.
Earlier Tuesday, St. Louis police shot and killed another black man, just miles from Ferguson. In this case, police say a 23-year-old man allegedly stole from a convenience store, then approached two officers with a knife and said, "Shoot me now, kill me now."
The officers asked the man to stop and drop his knife before they fired.
Hip hop mogul Russell Simmons is OutFront. In an opinion piece on Huffington Post, Simmons explains his ideas for how Ferguson can heal relations between the black community and police.
An American has purportedly been beheaded by ISIS terrorists.
A video appearing to show the horrific killing of photojournalist James Wright Foley and the gruesome aftermath was posted online Tuesday by the terror group that has been moving across Syria and Iraq.
CNN has watched the video, and chosen not to air it, believing it's too graphic and too disturbing.
The terrorists go on to threaten the life of another American if President Obama doesn't end the U.S. airstrikes in Iraq.
Foley went missing while covering the conflict in Syria back in 2012.
CNN's Nick Paton Walsh is in Iraq with the latest.
