that are more vulnerable to crime. There are many different techniques that have been put into practice to prevent offences involving weapons occurring and some have been more successful than others. One situational crime prevention to help prevent knife crime is the introduction of knife arches into public places. Knife arches are walk through metal detectors that sense if a person has metal on their body and alerts the people in charge, this means that if somebody is carrying a weapon on their persons, it will be detected and can be seized (Insight security, 2018). With the increase in offences involving weapons within the UK and the rise in people carrying knives, knife arches are seen to be being introduced into more public places, for example at school gates. With the majority of knife and gun crime offences being offenders aged 25 or under, the police have to target the places where these offenders will be and tackle them from the younger ages. More London schools are installing knife arches into their school gates to try and prevent children bringing weapons into school either to protect themselves or use against people (Dodd, V., 2017a). This can be effective in preventing offences involving weapons as they are changing the immediate environment in which children are taking the weapons to school and using them against each other. With the use of the knife arches it means they cannot get on the premises without being checked and their weapons being seized. However, there are critics that suggest knife arches are not effective in preventing offence involving weapons, instead they simply displace the possession of weapons to places that are not targeted. Superintendent Logan (cited in Dodd, V., 2017) states that having knife arches will mean the weapons are hidden outside of the school grounds and the crimes will be committed elsewhere – not many stabbings or shootings occur within schools so the police “need the intelligence to find the weapons” and put prevention in where the hotspots are. Another situational crime prevention approach is restrictions on the sales of knives in shops on the high street. The government states that it is “illegal to sell a knife to anyone under 18, unless it has a folding blade 3 inches long or less” (Criminal Justice Act, 1988). This law means that it is restricting the sale of knives so the younger people cannot buy them and use them inappropriately. However, even though there is a restriction on sales in shops, there is no restrictions on sale over the internet, thus meaning children under the ages of 18 can order knives and get them delivered to their houses without being stopped. With the common age of offenders and victims involving weapons being under the age of 25 (Office of National Statistics, 2017), the government are currently proposing a new legislation to make it illegal for knives to be delivered to home addresses (Lipscombe, S., Brown, J. and Allen., G., 2018). However, a large amount of people believe the restrictions on purchasing offensive weapons in shops or online, does not work in preventing offences involving weapons. At the proposal of banning home delivery of knives, many critics stated that it will not affect >
