Back in 2016, the United States Department of Justice reported that over 69% of law enforcement agency vehicles had dash cams, or in-car video systems for law enforcement professionals, installed. At the time, dash cams were still considered somewhat of a newer tool in the police arsenal. Why Consider Dash Cams for Law Enforcement Agency […]

On February 26th 2021, Tulane resident John Shallerhorn robbed someone in the parking lot of Carver High School and then shot Tulane policeman Martinus Mitchum in the chest, killing him. Eerily, two New Orleans Police Department officers had a strange conversation with the killer earlier the same day, and both incidents were captured on body cameras.

In the reaction above, zinc is being oxidized by losing electrons. However, there must be another substance present that gains those electrons and in this case that is the sulfur. In other words, the sulfur is causing the zinc to be oxidized. Sulfur is called the oxidizing agent. The zinc causes the sulfur to gain electrons and become reduced and so the zinc is called the reducing agent. The oxidizing agent is a substance that causes oxidation by accepting electrons; therefore, its oxidation state decreases. The reducing agent is a substance that causes reduction by losing electrons; therefore its oxidation state increases. The simplest way to think of this is that the oxidizing agent is the substance that is reduced, while the reducing agent is the substance that is oxidized as shown in Figure \(\PageIndex{1}\) and summarized in Table \(\PageIndex{1}\).

Law enforcement agencies around the globe have been deploying robots and drones to remotely enforce quarantine restrictions. Let’s look at some examples.

The 2020 lockdowns saw a sharp increase in speeding and road fatalities across the US, and this trend is yet to reverse. Why are American drivers still speeding, and what can we learn from the traffic statistics?

Apr 16, 2015 — The first and most obvious was that being tased hurts more than anything has ever hurt. However, the pain was gone as soon as that five-second ride ended.

However, there were two sets of BWC footage to support the officers in both of these cases. In terms of the arrest, the footage clearly shows that the officer simply reached through the suspect’s open door and pulled her out, never once setting foot on her property. Secondly, the footage showed that the officer did, at first, mis-speak when reading the suspect her rights. However, it also showed that he later corrected himself and re-read the rights. The arrest was deemed lawful and the suspect’s statements were deemed admissible in court, all due to the evidence provided by the BWCs.

Body worn cameras (BWCs) have been shown to have multiple advantages for police officers. They’ve been proven to aid in de-escalating situations, as people change their behavior when they know they’re being filmed. BWCs have reduced frivolous and unsubstantiated complaints against officers who use them. They’ve also helped to improve relations between police and their communities, by adding a layer of transparency and accountability.

Shallerhorn flagged down two NOPD officers that day, asking the female officer to come to his car. “I have my buddy here in the back seat, and — um — we were talking about the spirit, and I wanted — uh — your opinion,” Shallerhorn told Officer Alyssa Van Lew, according to video captured by her body-worn camera. Officer Van Lew told him they were responding to a 911 call and didn’t have time.

Life on planet Earth is a complicated and well-organized set of processes. Animals are designed to breathe oxygen and plants are designed to produce oxygen. Photosynthesis is the means by which we get the oxygen we need for life. Light striking a plant pigment known as chlorophyll initiates a complex series of reactions, many of which involve redox processes complete with movement of electrons. In this series of reactions, water is converted to oxygen gas, and we have something to sustain our lives.

In an article posted by www.thisweeknew.com, the Reynoldsburg Division of Police have begun utilizing Vantage body worn video for all patrol officers and supervisors beginning May 11, 2019. Their policy has officers activating the cameras during “calls for service involving citizen interaction, traffic and crime interdiction stops and ‘all enforcement and investigative contacts, including stops and field interview situation,’ according to the department’s policy. “

But of course, the main advantage of body cameras is in evidence collection. Having a camera operating at all times not only helps in picking up events that might otherwise have gone unnoticed, but also in creating a full, objective record of any incident the officer is present for. Here are three examples of times when BWC footage was a key element in upholding the law.

The officers went back over their BWC footage and found their encounter with the man. While speaking to him, the man had mentioned his name. With both a name and image, the officers were able to quickly identify and then track down the 31-year-old man. He was subsequently located and arrested on a series of outstanding warrants. The St. Thomas Police praised the BWC footage, saying that this was an example of body cameras directly helping in solving crimes.

What is oxidation and reduction

Shallerhorn walked away, but would later shoot and kill officer Martinus Mitchum who was providing security at a high school basketball game. Officer Van Lew’s camera footage shows a bulging object in Shallerhorn’s waistband. The object was most likely a pistol, and suggests that Shallerhorn was planning at least a couple of times that same day to ambush police officers. Shallerhorn was booked with first-degree murder of a police officer and armed robbery.

Break the reaction down into a net ionic equation and then into half-reactions. The substance that loses electrons is being oxidized and is the reducing agent. The substance that gains electrons is being reduced and is the oxidizing agent.

When chlorine gas is bubbled into a solution of sodium bromide, a reaction occurs which produces aqueous sodium chloride and bromine. Determine what is being oxidized and what is being reduced. Identify the oxidizing and reducing agents.

In 2016, police officers in Wisconsin arrested a woman on involuntary manslaughter and assault charges. The involuntary manslaughter was due to drunk driving, and the charges carried a possible sentence of eight to ten years. However, the suspect contended that the officers illegally entered her home to effectuate her arrest, and that statements she had given were inadmissible due to her Miranda being violated.

Almost 11 million people are held in penal institutions throughout the world, of which nearly 20% (2.12 million people) were incarcerated in the US (followed by China with 1.65 million).

On October, 8, 2021, police in St. Thomas, Ontario were investigating a break and enter at a local residence. Fortunately, the property’s security cameras captured footage of the break-in. When the officers were shown the surveillance footage, they noticed that the person on the footage beared a striking resemblance to someone they had dealt with earlier that same day.
