|Helmet tips for bike cops|
International Police Mountain Bike Assoc.
1. Wear one: the reason is obvious.
2. Remember that your helmet adds inches to the top of your head. If you find yourself in a tactical situation that may require you to take a quick, stealth peek around a wall, take your helmet off to decrease your chances of being spotted.
3. When making contact with a subject, undo the chin strap to prevent him from grabbing it during an assault.
