Ok, David, we don't disagree about that.
We are looking at it from two opposite sides, though.
Your premise is that less training time and money can be spent if we go back to revolvers for primary carry by LEO's.
My premise is that it is better to afford more training time and money. I'd rather train the officer to a level where he can quickly clear a jam or get his BUG in play.
I prefer my way, conceptually. Your way may more realistically reflect the amounts of money and effort PD's and LEOs are willing to put forth.
(Of course, I would also like to see more regular training in unarmed tactics for LEOs... in addition to more training in how to use basic psychology and common courtesy to de-escalate situations with a higher success rate)
