SANFORD, Fla. -

Jurors found George Zimmerman not guilty Saturday night. Children who did not understand the law, but were with their parents in front of the Seminole Court house were confused.

The jury of six women -- including five mothers -- unanimously agreed to find the 29-year-old former crime watch volunteer innocent in the death of 17-year-old Trayvon Martin. Zimmerman claimed  he killed him in self-defense.

Prosecutors charged him with second-degree murder and asked the jury to consider the lesser charge of manslaughter. A crowd of dozens of protesters gathered outside waiting for the news. It was dark and dozens of deputies surrounded them. 

After the verdict, Joseph Doneberg said he was angry.

"I'm in shock. I cannot believe the jury believed all of his lies," Doneberg said, while his 15-year-old son Aaron stood nearby quiet.

While a mother cried and her children walked around confused holding signs that read "Justice for Trayvon," reporters with their cameras and lights swarmed in after the verdict.

"This is an insult to all of the mothers in this country," Tamika Scott said while crying. Her seven-year-old son sat on the edge of the fountain.

There were many other children in the crowd. Reporters and their parents were distracted. A boy cried, as he stood behind his mother.

"I'm mad and sad," 11-year-old Alonzo Scott said in tears. "George Zimmerman killed Trayvon because he was black -- he was black. He wasn't doing anything. He was buying Skittles."

Shedrick Berfect, 10, and Daniel Berfect, 7, spent the day in front of the courthouse with their mother.

"I'm so, so, so, sad," Daniel said. "It's not fair that someone does something bad and doesn't get in trouble for it. He is going free."

Shauntiana Stafford, 11 and her 10-year-old brother Linzey said they had spent the entire afternoon in front of the courthouse.

"I thought when some one kills, they go to jail," Shauntiana said. "George Zimmerman killed a boy. I don't understand. This makes me mad."

Linzey wore his black and gray hoodie.

"I wore it in honor of Trayvon," Linzey said. "I will always remember him."
