The best patrol bag I ever used was a Costco laptop/school bag. Way easier to carry out to the car. I could still fit tape measure, DNA kit, fingerprint kit, posse box, ticket book, map, parking cites, pens, pencils, batteries, spare mag in a side water bottle holder, and a few other things that didn't go in the war bag. The old school square bag is too awkward and LEDs itself to throwing too much **** into it. After 5 years I realized the hazmat book was out of date AND I would never go near a scene like that. That's what hose draggers are for.
