And how come we didn’t hear the three shots??
****************************
I heard 2 shots, but I may have heard 3 shots - if that’s the case, then two of ‘em happened really close together... In other words, IDK.
I know that for many years, two shots (sometimes called a "double tap") has been the standard practice in combat shooting, with some organizations actually training to do "triple taps." Most good LE shooters are fast enough with a "double tap" to confuse anyone who doesn't follow such things closely. I have myself witnessed a few people getting three controlled, effective shots off in less than a second on a closed range, and a lot of John & Jane Q. Publics who were not paying particular attention to such a thing might testify that they heard only one shot.
In the past, too many officers died after firing one shot, thinking they had put their opponent down for good. When people whine and moan about multiple shots, the reality is that "one and done" defensive shooting is neither practical nor effective anymore.
