use. Unlike constables, due to the non-confrontational nature of their role PCSOs are not normally issued with batons, incapacitant spray, handcuffs or leg restraints. However PCSOs are authorised to carry and use this equipment. Four forces are an exception to this convention: British Transport Police PCSOs are issued with handcuffs and leg restraints; Also Dyfed-Powys Police, North Wales Police and Merseyside PCSOs are issued with handcuffs. Forces such as South Wales Police also issue 'Biteback' dog spray. Most police forces allow some PCSOs to use laser and radar guns to help enforce speed limits. Powers PCSO powers vary between forces. The powers of PCSOs mainly stem from the Police Reform Act 2002, and every PCSO since 2007 has a number of standard powers that were introduced for all PCSOs regardless of which force they belong to. This is in addition to the discretionary powers that can be designated by the chief constable or commissioner of each PCSO's respective force. Before 2003, the British Transport Police was unable to have PCSOs until Section 28 of the Railways and Transport Safety Act 2003 allowed the BTP Chief Constable to recruit PCSOs and designate powers to them using the Police Reform Act 2002—which previously only extended to chief constables or commissioners of territorial police forces. PCSOs must adhere to certain standards. Failure to do so could result in disciplinary or criminal proceedings related to misfeasance in public office or malfeasance in public office. Leeway may be given depending on the situation, as the circumstances may dictate they do not have the training or equipment to deal with a situation like a constable could. It is also accepted that PCSOs do not have to intervene in high risk situations and it is reasonable if they decide to withdraw from one. This is due to the non-confrontational purpose of their role. PCSOs are not attested constables, and therefore do not have the same powers of arrest under section 24 of the Police and Criminal Evidence Act 1984. They can, however, utilise the 'any person' powers of arrest under section 24A of the Police and Criminal Evidence Act 1984 (commonly known as a citizens' arrest). This means they are able to arrest anyone without warrant providing there are reasonable grounds to suspect they are committing, or have committed or are suspected to be guilty of an indictable or 'either-way' offence, provided the necessity criteria set out
