I use this for CERT team activities so I can't vouch for it's police patrol qualities. However, I lug around radios, batteries, electronic accessories, manuals, pencils & pens, notebook, water, snacks, wipes, first aid kit, CPR mask, safety goggles, dust mask, paracord, storage type clipboard, work gloves, safety vest, flashlight, head lamp, and a few other items.
I'm impressed by this durable bag. It has 4 rubber feet on the bottom, smooth working zippers and high quality velcro closures. The shoulder strap is comfortable as well. The 3 section divider is strong and easy to insert or remove.
I'm really glad to have found this bag - it's just right!
