The results also showed that Taser exposure caused significant negative change in several subjective state self-measures, including concentration difficulty, anxiety level and feeling overwhelmed. The significant findings in the subjective state measures raise the possibility that emotional factors after Taser exposure are important and may affect test performance.

ANPR systems are also used commonly in car parks to recognise number plates and issue fines and penalties for illegal parking or overstaying car park times. They can check a number of things, including:

“When police take suspects into custody, they read them their Miranda rights, which state that suspects have the right to remain silent, and anything they say can and will be used against them in a court of law,” said Kane. “The findings from this study suggest that people who have been shocked with a Taser may be unable to understand and rationally act upon his or her legal rights, and may be more likely to waive their Miranda rights directly after Taser exposure or to give inaccurate information to investigators. These decisions can have profound impact on an eventual judicial finding of guilt or innocence.”

At Viofo we have a variety of different cameras for enhanced security, including our 3 channel dash cameras that offer front, rear, and interior recording.

What happens if you get tased in the head

It is important to note that the camera systems used will vary from force to force and likely will change depending on the location of the forces, and their particular role, as well as the vehicle they use.

The researchers suggest a public dialogue about how to best integrate the Taser into everyday lawful policing in ways that maintain officer safety while reducing potential social costs incurred by suspects exposed to a Taser discharge. They ask: “What would it cost police to wait 60 minutes after a Taser deployment before engaging suspects in custodial interrogations?”

New research from a first-of-its-kind human study by Drexel University and Arizona State University reveals that the burst of electricity from a stun gun can impair a person’s ability to remember and process information. In a randomized control trial, participants were subjected to Taser shocks and tested for cognitive impairment. Some showed short-term declines in cognitive functioning comparable to dementia, raising serious questions about the ability of police suspects to understand their rights at the point of arrest.

Participants showed the greatest variability on the Hopkins Verbal Learning Test, which can indicate anything from mild learning impairments to dementia by measuring a person’s ability to learn new information (a string of words) and then recall that information after different intervals of time. The results indicate that Taser exposure caused statistically significant reductions in verbal learning and memory. The effects lasted, on average, less than one hour.

“Tasers are a great alternative to deadly force. When used in lieu of firearms, Tasers can save lives,” said Kane. “But using a Taser is not without risk. Although they are considered safe when used on healthy people, people have died from being Tased. They should be treated as a dangerous weapon.”

Police body-worn cameras are also increasingly being used by police officers in the UK. These small, wearable cameras can be clipped onto an officer’s uniform and are used to record footage of an officer’s interactions with the public.

Despite widespread adoption by law enforcement – stun guns are now used in 17,000 police departments – little is known about exactly how the shocks affect individuals’ cognitive functioning, or, more specifically, how receiving an electric shock from a Taser might affect the ability of a suspect to understand and waive their Miranda rights.

While short-term, the severity of the disruption was considerable, according to the researchers. The mean score for each group at pre-test was 26 – just above the national average. At post-test, one quarter of each Taser group scored below 20 on the HVLT, which represents the mean level cognitive functioning for 79-year-old adults, placing participants within the range of mild cognitive impairment. White said “our test administrators could clearly observe the difficulty many participants had with the HVLT after Taser exposure.”

Other systems used are ANPR cameras, which are used to detect and record the number plates of vehicles. These cameras are typically mounted on police cars and can be used to automatically check if a vehicle is stolen, untaxed or uninsured.

The police in the United Kingdom have been using dashcams since 2013, when they were first trialled in North Wales. The trial proved to be successful and since then, dashcams have been gradually rolled out to police forces across the country. The police and other forces will use different tech with enhanced features in order to make their job easier.

The participants were randomly divided into four groups. A control group of 37 participants did nothing, 32 people hit a punching bag to simulate the heightened physical state one might expect in a tense police encounter, 35 received five-second shocks and 38 hit a punching bag and received five-second shocks.

While the definite answer of ‘what’ camera the police use remains unsure, the fact remains that the police do use dash cameras and can vouch for their many benefits. If you’d like to add that extra layer of security on the road, you can browse our dash cameras here. View our handy dashcam buying guide here.

Given the nature of their job, police officers will need to have efficient and high-quality dash cameras in order to perform their duties properly. While there is a general lack of clarity regarding what dashcam the police use, we’ve compiled this blog to answer this as best we can.

Each participant completed a battery of cognitive instruments at a preliminary screening stage, immediately before treatment exposure, immediately after completion of their treatment condition, one hour later and one week later. The research team assessed participants’ scores both within and across groups over time to assess change in cognitive functioning.

To examine the effects of the Taser, the researchers recruited 142 participants who were required to undergo intensive screening protocols, including those for drug use and cardiac and psychiatric problems. According to White, “the study involved an elaborate admission process with significant protections in place to insure participant safety.” The randomized control trial was conducted at a hospital, with nurses and a physician on hand in case of emergency.

What doesa Taserdo to the body

The IVCS is typically used by police officers to record their interactions with the public, as well as to gather evidence at crime scenes. The footage recorded by the IVCS can be used in court proceedings and can be used to help investigate complaints against the police.

The questions driving this study involve serious issues including constitutionally protected rights of the accused, use of force by police and previously unexamined effects of the Taser on the human body.

While there is no one specific dashcam that is used by all police forces in the UK, the dash cameras that the police forces use will need to meet enhanced criteria. The dash camera systems used by the police will be far superior to regular dashcams and will have features to check:

“The findings of this study have considerable implications for how the police administer Miranda warnings,” said Kane. “If suspects are cognitively impaired after being Tased, when should police begin asking them questions? There are plenty of people in prison who were tased and then immediately questioned. Were they intellectually capable of giving ‘knowing’ and ‘valid’ waivers of their Miranda rights before being subjected to a police interrogation? We felt we had moral imperative to fully understand the Tasers’ potential impact on decision-making faculties in order to protect individuals’ due process rights.”

“Being shocked had a traumatic effect on some participants,” said Kane. “Some were emotionally debilitated by the experience.”

The study informs public policy in the area of police interrogations, specifically addressing the length of time police departments wait before interviewing suspects who have been Tased by police officers.

Funded by the U.S. Department of Justice’s National Institute of Justice, it marks the first time that the Taser has been submitted to a major randomized clinical trial on a community sample outside the purview of Taser International.

The footage recorded by body-worn cameras can be used as evidence in court proceedings and can also be used to help investigate complaints against the police.

The researchers point out that study participants were high-functioning, healthy young people who were accustomed to test taking and were sober and drug free at the time they were Tased, and thus, were functioning at a much higher level of cognition than do the ‘typical’ suspects in the field who experience Taser exposure at the hands of police officers. “We would expect ‘typical’ suspects – who may be high, drunk or mentally ill and in crisis at the time of exposure – to experience even greater impairment to cognitive functioning as the result of Taser exposure,” said Kane.

The police in the United Kingdom use a variety of dashcams in their patrol cars. The most common type of dashcam used by the police is the In-Vehicle Camera System (IVCS). The IVCS is a small, handheld camera that records video and audio footage from inside the police vehicle.

More than two million citizens have been Tased by police as Taser stun guns have become one of the preferred less-lethal weapons by police departments across the United States during the past decade. But what does that 50,000-volt shock do to a person's brain?

The study, “TASER Exposure and Cognitive Impairment: Implications for Valid Miranda Waivers and the Timing of Police Custodial Interrogations,” was published this month in the journal Criminology & Public Policy. The full article is available here.
