in the uk, yes in principal , if the officer isn't acting with in his powers then you can defend yourself. If the arrest or the amount of forced used was judged unlawful then you fighting back would be law full. Security in my this country have exactly the same powers as an ordinary person. that is they have a power of arrest if you have committed a indictable offence. So not for low level crime and if it turns out you hadn't committed a crime their arrest would be unlawfully. And therefore if you had fought back you would be in the clear. God only knows with airports, but if you are judged a trespassers and refuse to leave, then force can be used to make you
Ah 'security' in this country, well they wouldn't have been on the plane to start with nor would have police officers ( you want me to send police officers to remove a gentlemen who is causing no problems just because you want his seat for a staff member? yeah right that is going to happen...not).
As for 'officers not acting on their powers' well police officers here know their powers and they won't being acting outside them because of the bother, paperwork and sheer fuss that happens, you needs that sort of pain? 'Citizens' arrest is no longer the term used here. A police officer will always arrest that person anyway whether or not you arrest them as a 'citizens' arrest. Security officers should know the conditions under which they can 'arrest'.
apart from 'indictable 'offences, a civilian can also arrest someone under common law ( this is English and Welsh law btw, I'm not up on Scottish law having never worked there) if they are
(a) causing physical injury to himself or any other person; (b) suffering physical injury; (c) causing loss of or damage to property; or (d) making off before a constable can assume responsibility for him. As well as (a) a breach of the peace is committed in his presence, (b) the person effecting the arrest reasonably believes that such a breach will be committed in the immediate future by the person arrested, or (c) a breach of the peace has been committed or the person effecting the arrest reasonably believes that a breach of the peace has occurred and that a further breach is threatened.
The Police & Criminal Evidence Act 1984:
24A Arrest without warrant: other persons
(1) A person other than a constable may arrest without a warrantā
(a) anyone who is in the act of committing an indictable offence;
(b) anyone whom he has reasonable grounds for suspecting to be committing an indictable offence.
(2) Where an indictable offence has been committed, a person other than a constable may arrest without a warrantā
(a) anyone who is guilty of the offence;
(b) anyone whom he has reasonable grounds for suspecting to be guilty of it.
(3) But the power of summary arrest conferred by subsection (1) or (2) is exercisable only ifā
(a) the person making the arrest has reasonable grounds for believing that for any of the reasons mentioned in subsection (4) it is necessary to arrest the person in question; and
(b ) it appears to the person making the arrest that it is not reasonably practicable for a constable to make it instead.
(4) The reasons are to prevent the person in questionā
(a) causing physical injury to himself or any other person;
(b) suffering physical injury;
(c) causing loss of or damage to property; or
(d) making off before a constable can assume responsibility for him.ā
In relation to England and Wales, the expression "indictable offence" means an offence which, if committed by an adult, is triable on indictment, whether it is exclusively so triable or triable āeither wayā; and the term "indictable", in its application to offences, is to be construed accordingly. There is no simple definition.
An either way offence allows the defendant to elect between trial by jury on indictment in the Crown Court and summary trial in the Magistrates' Court. However, the election may be overruled by the Magistrates' Court if the facts suggest that the sentencing powers of a Magistrates' Court would be inadequate to reflect the seriousness of the offence. These offences can be the subject of an arrest.
as for trespass that is more complicated, in England you can't just chuck someone off your land forcibly, there has to be reasons to do it.
Section 61 CJPOA (Stones: 8-24900) enables a police officer to direct trespassers on land (who are there with the common purpose of residing there for any period) to leave the land where the occupier has taken steps to ask them to do so, and either:
- they have damaged the land; or
- they have used threatening, abusive or insulting behaviour to the occupier, the occupier's family, employees or agents; or
- between them they have 6 or more vehicles on the land.
Failure to obey a direction to leave or returning to the land as a trespasser within 3 months is an offence.
Section 62 provides a power for the police to seize vehicles of persons failing to comply with a direction under s6 1.
The senior officer present at the scene has to believe that the conditions set out in s 62(1) have been fulfilled. Evidence that they were fulfilled in fact will be relevant only in an inquiry into the questions whether the senior officer held the belief and whether, if he or she did, the belief was reasonably held. A defendant charged with an offence under the section (or, for example, charged with assaulting a police office in the execution of her or his duty) will be entitled to raise these questions. Although a successful defence along these lines is likely to be rare, the senior police officer will need to provide evidence in all cases justifying his or her giving of a direction.
