Police use Breathalyzers to determine a person's blood alcohol content (BAC). Breathalyzer is actually a trademarked name, but it is commonly used to refer to any device that measures BAC from a breath sample. Since Breathalyzers only provide an estimation of a person's BAC, police often request blood analysis to be used in court.

In 1908, the Detroit Police Department became the first to utilize motorcycles. The popularity of motorcycles for law enforcement and military purposes grew during WWI when Harley-Davidson sent nearly 20,000 motorcycles overseas to help the war effort. Then and today, motorcycles allow for increased responsiveness and maneuverability. Motor patrol officers are able to more easily investigate traffic-related incidents in comparison to four-wheeled police vehicles.

Because sudden cardiac arrest claims so many lives every year, police have begun carrying automated external defibrillators (AEDs) in their squad cars. A person's chance of survival dramatically decreases with each minute they do not receive defibrillation following cardiac arrest. That's why it's vital first responders have AEDs to perform this potentially life -saving procedure.

Officially known as a tire deflation device, a spike strip is used to slow down or stop a moving vehicle by puncturing its tires. The strip is made of upward pointing metal barbs that can be as long as 3 inches. Because they can be dangerous to set up, remotely deployable spike strips have been invented.

Often installed in collision-prone intersections, red light cameras photograph vehicles that enter an intersection after the traffic light has turned red. To record the infraction for later prosecution, the camera takes a picture of the vehicle's rear license plate. Before the driver is issued a ticket, a police officer reviews the footage to ensure a traffic violation actually occurred.

Intended as a non-lethal alternative, police most commonly use rubber bullets for riot control. They can be fired from standard firearms as well as riot-specific guns. Rubbers bullet may be considered "non-lethal," but they still cause bodily injury ranging from bruises and abrasions to bone fractures and internal bleeding. In a few cases, being struck with a rubber bullet has resulted in death.

In their early days, it took a team of strong men to operate a battering ram. Today, modern battering rams require just one or two people due to technical enhancements that magnify momentum. Police utilize battering rams when speed of entry, such as in hostage situations or stealth operations, is more important than preventing property damage.

1. Unmarked car

As their name suggests, riot shields are generally used in riots situations when police are trying to disperse an unruly crowd. A typical riot shield is tall enough to cover an average-sized person from head to knees. In addition to protection from thrown objects and non-ballistic weapons, riot shield can be used to physically push back rioters.

Also known as a tether, defendants placed under house arrest are often required to wear ankle monitors. The ankle monitor is programmed to notify police if the wearer moves outside a designated range. Some defendants have attempted to remove their ankle monitors, but the devices are extremely durable and resistant to tampering. Police are alerted if the wearer tries to cut the band or slip off the device.

   Tear gas

Like rubber bullets, tear gas is considered a non-lethal weapon and is most frequently utilized for riot control. Tear gas attacks the nerve of the lacrimal gland, forcing it to produce tears. While international treaties prohibit the use of chemical weapons such as tear gas in warfare, international law does not bind police from using it.

A more recent addition to police equipment, tasers are becoming more popular due to their ability to subdue a person without causing lasting physical harm. Police tasers can travel approximately 15-25 feet. Taser probes are able to penetrate most articles of clothing and emit an initial charge of up to 50,000 volts. However, by the time the electric shock reaches the intended person, it has usually diminished to around 1,800 volts.

Similar to traditional handcuffs, PlastiCuffs, or plastic handcuffs, are a physical restraint. Due to their primary material, PlastiCuffs are cheap and easy to manufacture. Police use plastic handcuffs in situations where many arrests are made in a short amount of time. Unlike traditional handcuffs, PlastiCuffs are much more vulnerable to breakage and unlawful removal.

As departments move toward the future of policing, some have elected to invest in thermal imaging cameras. Their primary function is to identify heat sources and do so by converting infrared radiation to visible light. From locating fleeing suspects to finding the source of a fire, thermal imaging cameras have a variety of uses.

Police often wear body cameras to more easily gather evidence at a crime scene as well as record their interactions with civilians. Like dashcams, some body cameras begin recording when an officer initiates a certain procedure. While body cameras vary greatly depending on the manufacturer and police department, some features include infrared, night vision and HD quality. Weighing anywhere from 2 ounces to 5 ounces, body cameras are lightweight so as not to restrict the officer in any way.
