I was watching ID the other day where a guy kidnapped a young girl, right in front of her sister, just half a block from her house, and with neighbors watching. It was a reenactment of course, but it literally took only 5 seconds. The man actually grabbed the girl as she was rollerblading past his truck. He waited until she was right in front of the door, swung it open, stepped out and grabbed her and stuffed her in the truck and sped off. FIVE seconds. Her sister was watching the whole thing, and the older half-sister who was inside, ran out when the other sister screamed, and saw the truck driving away. She started yelling, "He took her!" Two men were just down the street talking, one sitting in a vehicle and the other standing to the side. The man who was standing jumped into his vehicle and tried to follow the perp's truck but the perp managed to lose him eventually.
Four eyewitnesses. Five seconds. The guy managed to evade police for quite a while before they caught up with him. He had borrowed the truck he used to kidnap the little girl, from his boss at a construction site. He cleaned and vacuumed the truck, but LE found one long blonde hair that matched the victim's under the seat.
It can happen so fast!! And people watching from a block away might not even realize what is happening.
