6 year old boy calls 911 on dad

This wasn't the kind of emergency Joleen McDonald had in mind when she taught her 6-year-old son, Robbie, to dial 911.

When Robbie took a ride with his dad and saw him drive past a red light, he did what he thought was the right thing to do: He called the cops.

"My daddy went past a red light," Robbie said in a 911 call the Quincy Police Department in Massachuetts posted. "It was in the brand new car -- my mommy's car. We had to go to the car wash and then we went past the red light."

Mike Richardson and Robbie were on their way to a car wash last Saturday. The father stopped at a red light before taking a right turn. That's legal in Massachusetts.

But Robbie, who dreams of becoming a police officer, noticed his dad had driven by even when the light was red.

"He said he was going to call 911," Richardson told CNN. "I just kind of blew it off a little bit, you know, he's 6 years old."

When they got home, he called police.

"We were cooking on the grill," McDonald, told CNN. "Robbie went in the house and not even five minutes later he came out with the phone and was like, 'Somebody called.'"
