How facial recognition technology aids police

Police officers’ ability to recognize and locate individuals with a history of committing crime is vital to their work. In fact, it is so important that officers believe possessing it is fundamental to the craft of effective street policing, crime prevention and investigation. However, with the total police workforce falling by almost 20 percent since 2010 and recorded crime rising, police forces are turning to new technological solutions to help enhance their capability and capacity to monitor and track individuals about whom they have concerns.

One such technology is Automated Facial Recognition (known as AFR). This works by analyzing key facial features, generating a mathematical representation of them, and then comparing them against known faces in a database, to determine possible matches. While a number of UK and international police forces have been enthusiastically exploring the potential of AFR, some groups have spoken about its legal and ethical status. They are concerned that the technology significantly extends the reach and depth of surveillance by the state.

Until now, however, there has been no robust evidence about what AFR systems can and cannot deliver for policing. Although AFR has become increasingly familiar to the public through its use at airports to help manage passport checks, the environment in such settings is quite controlled. Applying similar procedures to street policing is far more complex. Individuals on the street will be moving and may not look directly towards the camera. Levels of lighting change, too, and the system will have to cope with the vagaries of the British weather.

[…]

As with all innovative policing technologies there are important legal and ethical concerns and issues that still need to be considered. But in order for these to be meaningfully debated and assessed by citizens, regulators and law-makers, we need a detailed understanding of precisely what the technology can realistically accomplish. Sound evidence, rather than references to science fiction technology --- as seen in films such as Minority Report --- is essential.

With this in mind, one of our conclusions is that in terms of describing how AFR is being applied in policing currently, it is more accurate to think of it as “assisted facial recognition,” as opposed to a fully automated system. Unlike border control functions -- where the facial recognition is more of an automated system -- when supporting street policing, the algorithm is not deciding whether there is a match between a person and what is stored in the database. Rather, the system makes suggestions to a police operator about possible similarities. It is then down to the operator to confirm or refute them.

The lion and the four bulls

Clarke, M.

    A lion used to walk about a field in which four bulls lived. Many times he tried to attack them, but whenever he came near, they turned their tails toward one another so that whichever way the lion tried to attack, he would have to face the horns of one of them.
    At last, however, the bulls started arguing with each other, and each went off to a different part of the field by himself. Then the lion attacked them one by one and soon had killed all four.

Ann Arbor: The University of Michigan Press, 1996.p.138

In the fragment “At last, however, the bulls...”, the word however means the same as:

Carregando...

In the sentence “And the store doesn’t accept cash, just good deeds.” (paragraph 1), the word deeds means

Memories

Maroon 5

Chorus:
Here’s to the ones that we got
Cheers to the wish you were here, but you’re not
‘Cause the drinks bring back all the memories
Of everything we’ve been through
Toast to the ones here today
Toast to the ones that we lost on the way
‘Cause the drinks bring back all the memories
And the memories bring back, memories bring back you
There’s a time that I remember, when I did not know no pain
When I believed in forever, and everything would stay the same
Now my heart feel like December when somebody say your name
‘Cause I can’t reach out to call you, but I know I will one day, yeah
Everybody hurts sometimes
Everybody hurts someday,
But everything gon’ be alright
Go and raise a glass and say,
Chorus
There’s a time that I remember when I never felt so lost
When I felt all of the hatred was too powerful to stop (ooh, yeah)
Now my heart feel like an ember and it’s lighting up the dark
I’ll carry these torches for ya that you know I’ll never drop, yeah
Everybody hurts sometimes
Everybody hurts someday,
But everything gon’ be alright
Go and raise a glass and say,
Chorus

The Last Kingdom

     The Last Kingdom is a contemporary story of redemption, vengeance and self-discovery set against the birth of England. The series combines real historical figures and events with fiction, retelling the history of King Alfred the Great and his desire to unite the many separate kingdoms into what would become England.
     Set in the 9th century AD, many of the separate kingdoms of what we now know as England have fallen to the invading Vikings, only the great Kingdom of Wessex stands defiant under its visionary King Alfred the Great. It is the last kingdom. Against this turbulent backdrop lives Uhtred. Born the son of a Saxon nobleman, he is orphaned by the Vikings and then kidnapped and raised as one of their own. Forced to choose between the country of his birth and the people of his upbringing, his loyalties are ever tested. What is he — Saxon or Viking? On a quest to claim his
birthright, Uhtred must tread a dangerous path between both sides if he is to play his part in the birth of a new nation and, ultimately, recapture his ancestral lands.
     The Last Kingdom is a show of heroic deeds and epic battles but with a thematic depth that embraces politics, religion, warfare, courage, love, loyalty and our universal search for identity. Combining real historical figures and events with fictional characters, it is the story of how a people combined their strength under one of the most iconic kings of history in order to reclaim their land for themselves and build a place they call home.

   The body of officers representing the civil authority of government is known as police. Police typically are responsible for maintaining public order and safety, enforcing the law, and preventing, detecting, and investigating criminal activities. These functions are known as policing. Police are often also entrusted with various licensing and regulatory activities. However, police scholars have criticized this popular understanding of the word “police” — that it refers to members of a public organization having the legal competence to maintain order and enforce the law — for two reasons. First, it defines police by their ends rather than by the specific means that they use to achieve their goals. Second, the variety of situations in which police are asked to intervene is much greater than law enforcement and order maintenance.
   There is now a consensus among researchers that the common feature among all the different agencies engaged in policing is the legal competence to enforce coercive, nonnegotiable measures to resolve problematic situations. Such situations are characterized by their potential for harm and the need to solve them urgently before they develop that potential. Hence, the actual use of coercion or the threat of using it allows police to put a quick, nonnegotiated, and conclusive end to problematic situations.

‘Emily in Paris’ star says he partly understands why critics panned the ‘cliché’ Netflix show

    Despite being a huge hit for Netflix, critics across the board (particularly French critics) have slammed the show for indulging in outdated and offensive stereotypes that present Parisians as rude, sexist, and elitist.
    The main love interest in Netflix’s controversial comedy “Emily in Paris” said he partly understands why critics have panned the show. “I think they’re right in a way,” Lucas Bravo, who plays chef Gabriel in the show, said during an interview with Cosmopolitan.
    The 32-year-old French actor continued: “At some point, if you want to tell a story about Paris, you have to choose an angle. You have to choose a vision. French critics, they didn’t understand the fact that it’s just one vision. They’re like, ‘Oh, this is not what Paris is.’ Of course. Paris is many things.”
