From the article:
Instead, gangsters - albeit unkowingly - use another method to get what's called a 'flash sight picture' by quickly aiming down the side of the gun barrel without perfectly lining it up with the target.
What a load of Hooey.
The flash sight picture uses the, uh ....... wait for it...... sights.
Pointing the gun at your target without lining up the sights is ..... point shooting.
I guess the bar to be an expert on shooting, in a country in which private ownership of guns is so severely curtailed that very few people actually know much about the subject, can be pretty low: In the land of the blind, the man with one eye is king.
