The Bill contains measures to ensure that police and local communities have the powers they need to tackle guns, knives and alcohol-related violence. These provisions include: Guns: Making it illegal to manufacture, import or sell an imitation firearm, other than one which no reasonable person would mistake for a real firearm. Introducing tougher manufacturing standards to ensure that imitation firearms cannot be converted to fire live ammunition. Introducing tougher sentences for carrying imitation firearms. Banning the sale of primers and specialist re-loading equipment used to assemble the components of ammunition to anyone without a valid firearm or shot-gun certificate. Requiring that air weapons are sold only through registered firearms dealers, and that all sales take place face to face. Tightening up the law on the indiscriminate and reckless firing of air-guns from private property. Increasing from 17 to 18 the age for acquiring or possessing an air weapon without supervision. Creating a new offence of using another person to hide or carry guns or knives. Knives: Raising the minimum age at which a young person can buy knife from 16 to 18. Raising the minimum age at which a young person can buy a crossbow from 17 to 18. Introducing a power for members of staff of schools, further education institutions and attendance centres to search pupils, students and persons attending the centres respectively for weapons. Introducing a defence for those supplying offensive weapons for film, TV or theatre productions. Alcohol-related crime and disorder: Introducing a new civil order - a 'Drinking Banning Order' - which will allow individuals who are responsible for alcohol-related disorder to be excluded from certain areas and from licensed premises. Enabling the creation of Alcohol Disorder Zones, in which licensed premises will be required to contribute to the costs of dealing with alcohol-related disorder in areas where this is a problem. Introducing a power for the police to require an expedited review of a premises licence where the premises are associated with serious crime and disorder, and a power for councils to take temporary steps in relation to the license (including imposing additional conditions) pending the determination of the review. Introducing a power for the police to impose 48-hour bans on pubs and clubs persistently selling alcohol to underage drinkers. Introducing a power for the police to issue on-the-spot 48-hour exclusions to those who represent a public order risk, or where there is a risk of their involvement in alcohol-related disorder.
