In 90% of shootings, a law-enforcement officer has less than two seconds react:
A common debate about practical defense-oriented shooting is whether a “speed draw” is really important. Some folks like to argue that their amazing power of awareness will protect them from any unplanned, unscheduled harm. However, an interesting tidbit comes from a recent article by Dr. Darrell Ross (professor and department head of the Department of Sociology, Anthropology, and Criminal Justice at Valdosta State University and Director of The Center of Applied Social Sciences) called Assessing Lethal Force Liability Decisions and Human Factors Research.
Professor Ross explains that in 90% of the 1,100 cases studied, an officer had less than two seconds to react to perceived lethal danger. (Law Enforcement Executive Forum, 2013, #13(2), p90)
