Deputy Marshal Samuel Gerard: Alright, listen up, people. Our fugitive has been on the run for ninety minutes. Average foot speed over uneven ground barring injuries is 4 miles-per-hour. That gives us a radius of six miles. What I want from each and every one of you is a hard-target search of every gas station, residence, warehouse, farmhouse, henhouse, outhouse and doghouse in that area. Checkpoints go up at fifteen miles. Your fugitive's name is Dr. Richard Kimble. Go get him. ..... From the movie "The Fugitive"
