Law Enforcement using Social Media!

An essay on Law Enforcement and Media.

The Internet has drastically changed the way investigation is done.  For many people, every aspect of their lives is recorded on their social media platforms.  This gives law enforcement incredible amounts of information about people and how to find them.  Some of this is direct information, and some indirect, but it all of it can be used to make the world a safer place.

The first and most obvious way that the Internet has changed the way criminal investigations are conducted is that sometimes people actually admit to crimes on social media.  In 2015, a woman in Florida recorded herself driving under the influence and posted this video onto social media.  The police arrested her the next day.  People like to brag about their lives, and sometimes they will actually post what they think they have gotten away with.  This makes law enforcement’s job very easy.

Even if they haven’t admitted to a crime, police officers can track known criminals and gang members on their social media accounts.  This second tool allows the prevention of crime via observation.  Gang members know that the police are watching their movements and so they will be more cautious about committing crimes in general.  The police will know where the people they are concerned about are and if they were in the area when a crime was committed.  This also allows them to keep track of people who are associating with groups like ISIS, or are liking webpages that talk about the use of weaponry.  Law enforcement can go on those pages and track the others who have liked them.

Another way that the Internet has changed things is that law enforcement does not necessarily need to find the specific person any more.  They can find someone close to them who is present on the Internet and build from there. Even when people do not post their own data, the people around them might.  A famous recent case would be catching the Golden State Killer.  He had escaped custody for decades, but because one of his relatives signed up for a DNA ancestry test online, law enforcement was able to track him down.  He did not sign up for this service, but because someone associated with him did, he was found.  Friends post pictures of friends on social media, and a reverse image search is going to find them.  Someone who never intended to have his or her picture on the Interne is now simply there for viewing.

One of the most useful tools becoming increasingly available is crowd sourcing.  Crowd sourcing is utilizing the resources of large groups of people to accomplish a common task.  Law enforcement can post a photo of who they are looking for, and citizens across the globe can be instantly informed.  They will share those photos across twitter and Facebook to reach entire communities, which allows people to be able to assist as never before in searching for accused people.  

In addition to these, the internet has changed investigations in that it can shorten the field of suspects based on information on social media servers.  Facebook categorizes people based on the sort of posts they like and look at.  They are categorized by political affiliation, inclination towards conservative or liberal ideas, interests, and more.  They do this so that they can target people with appropriate ads, but it also allows people to be found quicker.  All the data about what people enjoy, how long they look at videos or images, and what they specifically post is kept on Facebook servers.  Some of this data is public, and law enforcement officers can look at it.  Even private data can be inferred from what people post on social media.  If they are traveling and check in at an airport, or belong to a team and wear the logo in a picture, locations of people are not difficult to find.  Even simply a phone number is going to be associated with an area code and can be tracked.

The Internet and social media have changed the way our lives function, and it has also revolutionized law enforcement.  Investigators have many more tools available to them to solve crimes.  If these are utilized properly, law enforcement will be able to better capture and contain criminals.

Neuroscience research shows the brain is strobing, not constant

It’s not just our eyes that play tricks on us, but our ears. That’s the finding of a landmark Australian-led collaboration that provides new evidence that oscillations, or ‘strobes’, are a general feature of human perception.

While our conscious experience appears to be continuous, the University of Sydney and Italian universities study suggests that perception and attention are intrinsically rhythmic in nature.

This has profound implications for our understanding of human behaviour, how we interact with environment and make decisions.

A paper published in Current Biology provides the important new evidence for the cyclical nature of perception.

3 key findings:

auditory perception oscillates over time and peak perception alternates between the ears – which is important for locating events in the environment;

auditory decision-making also oscillates; and

oscillations are a general feature of perception, not specific to vision.

The work is the result of an Italian-Australian collaboration, involving Professor David Alais, Johahn Leung and Tam Ho of the schools of Psychology and Medical Sciences, University of Sydney; Professor David Burr from the Department of Neuroscience, University of Florence; and Professor Maria Concetta Morrone of the Department of Translational Medicine, University of Pisa.

With a simple experiment, they showed that sensitivity for detecting weak sounds is not constant, but fluctuates rhythmically over time.

It has been known for some years that our sight perception is cyclical but this is the first time it has been demonstrated that hearing is as well.

“These findings that auditory perception also goes through peaks and troughs supports the theory that perception is not passive but in fact our understanding of the world goes through cycles,” said Professor Alais.

“We have suspected for some time that the senses are not constant but are processed via cyclical, or rhythmic functions; these findings lend new weight to that theory.”

These auditory cycles happen at the rate of about six per second. This may seem fast, but not in neuroscience, given that brain oscillations can occur at up to 100 times per second.

“These findings are important as humans make decisions at the rate of about one-sixth of a second, which is in line with these auditory oscillations,” said Professor Alais.

The study found a variation of oscillation between the two ears, first one ear is at peak sensitivity, then the other. The oscillation is so fast that we are normally unaware of it, but can be revealed in experiments using very fine-grained timing.

Why should the brain sample information in this cyclic fashion? Theories abound, but one popular idea - favoured by the authors of this study - is that it reflects the action of attention which appears to sample neural activity in rapid bursts.

The scientists are next focusing their attention on perceptions of touch and how this might make use of neural oscillations as part of a goal of characterising perception in general over all the senses.

“The brain is such a complex ‘machine’ one could say – it is a testament to science that we are starting to make sense of it – but a takeaway could be that there is so much we don’t know,” Professor Alais concludes.

“A decade ago, no one would have thought that perception is constantly strobing – flickering like an old silent movie.“

For the moment, this research shows one thing very clearly: our sensory perception of the world is fundamentally oscillatory, like a strobing light or a wave waxing and waning.

The strobing brain – how it works

When we peruse a scene, not all parts are equally important: some receive more attention than others and are prioritised in processing. This is an effective strategy, concentrating limited cognitive resources on specific items of interest, rather than diluting resources over the entire space.

Similarly, oscillating attention would produce an analogous result over time, with resources concentrated into small temporal epochs instead of being sustained in a uniform but thin allocation.

This strobing approach to attention would bind together relevant information at regular time points and allow new groupings of information to reassemble at other moments.

Let’s say your matrilineal line is fairly consistent and everyone has their daughter at 25. So four women in your matrilineal line are born every hundred years. In a thousand years, that’s only 40 women. Like the math is so simple and yet ? You don’t think about it. So in 2000 years, 80 women. So basically, 0 AD started roughly about 80 mothers ago. That’s it.

Once again, parody presents a better argument for high heels than serious studios.

Not to mention, those heels are actually drawn by an artist capable of googling “tall stripper shoes” and designing something (awkwardly) wearable. 

instead of pulling foot-liquifying “jet boots” straight out of their behind.
