here is a snip from the study...it was a look at shootings at LEO.

It is fascinating read. There is a war in the tactics forum right now point shooting...
Shooting Style
Twenty-six of the offenders [about 60%], including all of the street combat veterans, "claimed to be instinctive shooters, pointing and firing the weapon without consciously aligning the sights," the study says.
"They practice getting the gun out and using it," Davis explained. "They shoot for effect." Or as one of the offenders put it: "[W]e're not working with no marksmanship..We just putting it in your direction, you know..It don't matter.as long as it's gonna hit you.if it's up at your head or your chest, down at your legs, whatever..Once I squeeze and you fall, then.if I want to execute you, then I could go from there."
Hit Rate
More often than the officers they attacked, offenders delivered at least some rounds on target in their encounters. Nearly 70% of assailants were successful in that regard with handguns, compared to about 40% of the victim officers, the study found. (Efforts of offenders and officers to get on target were considered successful if any rounds struck, regardless of the number fired.)

Missed Cues
Officers would less likely be caught off guard by attackers if they were more observant of indicators of concealed weapons, the study concludes. These particularly include manners of dress, ways of moving and unconscious gestures often related to carrying.
"Officers should look for unnatural protrusions or bulges in the waist, back and crotch areas," the study says, and watch for "shirts that appear rippled or wavy on one side of the body while the fabric on the other side appears smooth." In warm weather, multilayered clothing inappropriate to the temperature may be a giveaway. On cold or rainy days, a subject's jacket hood may not be covering his head because it is being used to conceal a handgun.
Because they eschew holsters, offenders reported frequently touching a concealed gun with hands or arms "to assure themselves that it is still hidden, secure and accessible" and hasn't shifted. Such gestures are especially noticeable "whenever individuals change body positions, such as standing, sitting or exiting a vehicle." If they run, they may need to keep a constant grip on a hidden gun to control it.
Just as cops generally blade their body to make their sidearm less accessible, armed criminals "do the same in encounters with LEOs to ensure concealment and easy access."
An irony, Davis noted, is that officers who are assigned to look for concealed weapons, while working off-duty security at night clubs for instance, are often highly proficient at detecting them. "But then when they go back to the street without that specific assignment, they seem to 'turn off' that skill," and thus are startled--sometimes fatally--when a suspect suddenly produces a weapon and attacks.
