New technology to tackle knife crime

Technology has the potential to drastically improve most aspects of life and in some cases, it can save lives. With policing and showing law enforcement, the aid of technology has proven to be significant. In recent years, UK’s knife crime has been rising at an alarming rate and using techniques like artificial intelligence could combat the numbers.


We all want to stop crime and catch criminals; however, it must be done without discrimination, harassment or a police state. Technology can prove to help deal with matters in a better way, but if it is misused it can lead to a lot of corruption and subsequently lead to a backlash in the advancement of technologies in this sector of work.


Facial recognition 

Predictive techniques could be extended with facial recognition. This would be a means of identification and would be able to narrow down targets. Although this sounds impressive, it opens up the possibility of violating human rights issues. The near real time recognition concept is not far away as body-worn cameras are still being actively used by police. Police believe the use of the body-worn cameras have helped cut out illegitimate complaints against their officers.

Weapon detection

Technology can also be used to detect weapons used in knife crime. Metal detectors are already available and are a big help to quickly checking people, but distinguishing concealed blades from other objects may be a problem for police. Home Office and Department for Transport have shared £460,000 among six companies to accelerate the innovative technology designs that are aimed to detect knife carriers in crowded places.


Different organisations and universities are supporting these causes as a lot of research and investigative work goes into finding solutions involving radar and electromagnetic sensors that can detect steel-bladed knives. If the technology reaches an advanced stage, these detection devices would greatly help with the tackling of knife crime.
