During a recent Senate Judiciary Committee hearing, FBI Deputy Director Paul Abbate revealed that SWAT observed shooter Thomas Crooks using a range finder before his assassination attempt. This revelation prompted Committee Chairman Dick Durbin to question the witnesses about the significance of the range finder in identifying Crooks as a dangerous individual.
When Durbin inquired about the purpose of a range finder, the response indicated that it is typically used to determine one's proximity to a fixed location. While it was suggested that the range finder in question might have been intended for recreational or sports purposes, it still provided Crooks with the crucial information of the distance between himself and his target.
