Figures are dependent on offences that have been reported and recorded by the police.
The data provided on this table refers to where a knife has actually caused an injury to the victim. The previous knife crime offences tables on the citizensreportuk.org site included knife offences where a knife was either seen or spoken of to threaten a victim.
Knife offences With Injury:All offences of Murder, attempted murder, threats to kill, manslaughter, infanticide, wounding or carrying out an act endangering life, GBH without intent, ABH and other injury, sexual assault, rape, robbery where a knife or sharp instrument (defined as any instrument that can pierce the skin) has been used and caused injury.
The “Knife Crime with Injury” category may provide a better indicator of potentially lethal knife use, rather than “knife homicides” or “knife crime with serious injuries”. A wounding from a knife in a seemingly non-lethal area can very easily lead to severe and fatal consequences dependent on access to medical care and whether a major artery or organ has been damaged. The element of chance means that any knife wound is potentially lethal but luck and skill of health services has prevented many of these stabbing injuries leading to fatalities.

Four thousand stabbings a year in London for the last three years is a staggering amount. That the number of fatalities (in the hundreds) is so low has to say something about both the intent behind the majority of the stabbings and the pace and skill of our NHS services (bless them and long may we keep them). Alas policing seems to be making little difference in reducing or preventing these stabbings and Mayor Boris is a blithering idiot who thinks more Latin classes is the answer to youth violence. There seems to be no long term strategy to get real reductions in stabbings and no robust theories as to why the level of stabbings in London has remained so high for so long.
What we learn from London stabbings is that too many people think its gonna be ok sticking a knife in someone whether that’s with intent to kill or not. The days of a punch up to settle an argument are well over and knives and gun use becomes the style of cowards. In my day those who resorted to knives and guns were seen as weak tossers who didn’t have the balls to face up to someone without resorting to weapons.
