Be it from gangs of drunken teenagers to more serious cases of vandalism, assaults or even murder, stories of problems involving young louts are rarely out of the newspapers.

However, coming up with an effective plan to deal with the troublemakers has proved difficult for politicians, police and local officials.

Anti-social behaviour orders (ASBOs) have probably been the best-known antidote the authorities have used. But experts say these have their limits and some serial offenders just view them as a “badge of honour”.

The latest initiative to get the backing of the government is a scheme to turn the tables on the yobs with the police hounding them to make their lives uncomfortable.

Residents in Essex, where the Operation Leopard idea was first introduced, say it was a great success.

But it is likely to alarm some civil rights groups, who have expressed concern about the use of ASBOs.

Cannabis was downgraded to Class C — which includes substances such as anabolic steroids — in 2004. That meant possession of the drug was treated largely as a non-arrestable offence. The Advisory Council on the Misuse of Drugs recommended it should stay as Class C.

Since 2004 there has been much debate on the dangers of repeated use of cannabis, the likelihood of its fostering psychotic behaviour and its role as a possible “gateway” to more dangerous drugs. 

Do you believe Gordon Brown is right in putting cannabis back in Class B? 

Under the first, Children’s Secretary Ed Balls proposes that trouble-makers as young as 10 should sign a good behaviour contract . The “most challenging” among them will have to stick to the order or risk a criminal record.

The second, more extreme, suggestion comes from Gary Pugh, forensic science director for the Metropolitan Police, who was quoted in The Observer as saying trouble makers as young as five should be recorded on the national DNA database because future offenders can be picked out an early age.

The idea has been widely criticised, both by those who dislike the idea of stigmatising children at such a young age and those who bemoan what they call the government’s obsession with compiling databases — and its embarrassing tendency to lose personal data. The government has been non-committal but says it is listening to all views.

Do you believe law enforcement authorities need more tools at their disposal to deal with unruly children?
