When i was 16 i chased down a robber. I was babysitting and a robber broke into the family's house.
As we started to enter the house the glass from the back door was on the floor to indicated robbery (my house had just been robbed 1 month earlier). They criminal fled the house on a bike. The kids and i jumped in the car and chased him down. He pretended to have a gun so i moved on quickly. Several weeks later i had to ID him in a lineup... Yikes that was when i was scared without all the adrenaline.
