A grand jury decided Monday that Police Officer Darren Wilson will not face criminal charges for killing unarmed teenager Michael Brown in early August.

Thousands of people took to the streets in cities throughout the U.S. protesting against the decision, but many voiced their opinions on the Internet/

Slate tweeted, "The simple fact is that the police can kill for almost any reason with little fear of criminal charges."

Roland S. Martin tweeted, "Like I said before: I am not shocked that the grand jury did not indict #DarrenWilson. VERY FEW cops are ever indicted in fatal shootings."

President Barack Obama pleaded with residents and police officers to show restraint in Monday's decision, pushing for peaceful protests only, Yahoo News reports.

"We are a nation built on the rule of law, so we need to accept that this decision was the grand jury's to make," Obama said.

The White House let out a statement late Monday saying that Obama calls for the police and their communities to work together.

"That won't be done by throwing bottles. That won't be done by smashing car windows. That won't be done by using this as an excuse to vandalize property," the president said. "It certainly won't be done by hurting anybody."

Magic Johnson tweeted, "We must work together to stop the unnecessary loss of young men of color. Justice was not served in Ferguson."

Some of the protesters smashed windows and vandalized police cars right after the jury decided to not convict a white police officer for killing an unarmed black teenager while others protested peacefully holding up signs that said, "Justice for Michael Brown."

Michael Eric Dyson tweeted, "A tragic decision to prevent the open airing of the evidence in the killing of an unarmed black youth, shot down by a cop with a gun."

After Wilson fatally shot Brown in August, protests for the officer's indictment went on for weeks.

"This is not just an issue for Ferguson, this is an issue for America," Obama said. "There are still problems, and communities of color aren't just making this up."
