If there's a need to get in close, or the offender gets in close then drawing your weapon across your body does two things...
1. takes longer (most of the time) to draw your weapon and
2. when you're up close, your arm can be restrained sufficiently to prevent the draw.
Most police officers are trained to draw and fire from a belt holster worn on their strong side.
As most site viewers are aware, practice is the strong suit in a stress situation.
Back in the day when snubbies were frequently deployed to plain clothes officers, a shoulder holster was quite common.
Today with heavier and somewhat bulkier pistols - not so much.
Plus the whole liability issue comes into play if an officer uses 'non-issue' kit while on duty.
With the amount of oversight on police today - anything that's not approved for use could bite an officer in the buttocks.
