The law protecting people who intervene in criminal situations is to be urgently reviewed, Justice Secretary Jack Straw is to announce.
He will say self-defence law works "much better than most people think, but not as well as it could or should".
Mr Straw wants to reassure victims or witnesses in England and Wales that they can use reasonable force to stop and detain offenders.
Well, that's just lovely. And what dictates reasonable force? Isn't that rather the problem? If someone breaks into my house, I might think that punching him to the ground and then clubbing him unconscious with a pool cue is reasonable force: unfortunately, I don't think that the law does, unless the burglar's first done the same to me.
However, if it allows people to hold thugs for arrest, without the little scrotes claiming that "you are infringing my rights an' I'm gunna get you done for it, mister" then that is probably a good thing.
"The justice system must not only work on the side of people who do the right thing as good citizens but also be seen to work on their side."
Quite. And, it turns out, Mr Straw is a bit of a hero himself.
Mr Straw has intervened four times to stop criminals, including three times when he managed to detain the offender.
In 1980 he overheard a burglar breaking into a members club in his Blackburn constituency, chased them down the street and detained them until police arrived.
In the mid 1980s at Oval Tube station in south London he came across an 11-year-old boy who had just been robbed by a man and detained the offender.
At the same tube station in the early 1990s he chased a man who had attacked a woman, but did not catch him.
Then in 1996 he chased a man who had robbed a member of the public and detained the suspect until police arrived.
Methinks that Mr Straw is being too modest! After all, some years ago, he also dragged a young scrote, who was dealing cannabis, to the police station.
The justice secretary will state: "Enforcing the law, securing justice, is not just a matter for 'them' the courts, the prisons, the probation service, police - but for all of us."
Well, yes, that's a lovely idea and I am sure that it would be good to encourage citizens to take action themselves; Boris will no doubt be happy with Straw's initiative.
The Association of Chief Police Officers, the Crown Prosecution Service, judges and other government ministers are expected to be consulted during the review.
Which is interesting, because the police's official line is that members of the public should not get involved at all.
