Arizona police, despite a serious discussion of weapons in American society, decided to mount semi-automatic AR-15s on their patrol bikes.

It looks very brutal and causes some panic among local residents. It’s one thing, when the rifles are in the trunk of a police car, and the other, when it is mounted on a motorcycle for everyone to see.

"People do notice. We've had both sides. We've had people concerned about how it looks. It looks militaristic," Sgt. Ronald Elcock told.

On the other hand, sometimes a police motorcycle usually comes first to the crime scene, so it is extremely important that they have the means to protect themselves and law-abiding citizens. For these reasons the Phoenix suburb’s police department opted to equip eight of its patrol bikes with AR-15s mounted on racks on the back of the motorcycles.

Moto-mounted officers are required to go through an additional 40 hours of training before being issued one of the motorcycles with weapons.
