Midway through reading now, its definitely something to peruse. http://www.wcvb.com/blob/view/-/32176196/data/3/-/4n9k3vz/-/Watertown-After-Action-Report.pdf Of interest to me was the events of the shootout in Watertown and what went right/wrong. The first thing that jumped out at me was: "The officers unsuccessfully attempted to remove their patrol rifles from the secure mounts in their vehicles, and returned fire with their handguns." Reading firsthand discussions of patrol rifle employment across the country is the importance of having the rifle ready BEFORE affiving at the scene. That means cabin mounts are vastly superior to trunk storage, but also have their drawbacks. Training should include retrieving, charging, and slinging the rifle while driving so it can be immediately deployed at the scene. This event occured very quickly once the officer made the initial contact, but imagine the advantage of the Sgt having 30 rounds of 5.56 from a braced firing position on the dashboard...such as the EPO did during the West Memphis Arkansas shootout with the cop killers. I don't know whether its policy or mindset that keeps rifles from being employed more often around here, but an armed carjacking suspect would certainly warrant a long gun in my mind (or shotgun...slugs are great on auto glass!) even better if it has a high intensity weapon light mounted (WHICH IT ABSOLUTELY SHOULD).
