POLICE Commissioner Gary Burns has moved to allay any public concerns over the recent shootings, saying in all cases they have been targeted, not random.

His comments come as a 35-year-old woman was arrested and charged over the shooting murder of Adrian Paul MacDonald at a Parafield car wash on the weekend.

Speaking before today's arrest, Mr Burns said police had ruled out the involvement of outlaw motorcycle gangs in the murder.

"We believe that this is another one of those targeted offences where it's not necessarily that it's (outlaw motorcycle gang) related or other motives but once again there is a tie up there.

"I can't give you the motive now because that's part of a Major Crime investigation.

Mr Burns stressed that the recent series of shootings were targeted incidents linked to either outlaw motorcycle gangs, drugs, debts owed or were domestic related.

He said that police had already seized 1334 illegal firearms since the start of July last year, in addition to 2783 of them that were handed in during a three-month amnesty last year.

Police have also made 470 arrests or reports for offences involving firearms since the start of July last year.

"The battle to remove illegal weapons from our community is constant and difficult, with no one easy measure to solve this complex issue," Mr Burns said.

"I assure you that police are dedicated in their resolve to take illegal guns off the streets.

"Police have been given extensive legislative tools by the Government to help curb both organised crime and gun violence. And late last year we set up a specialised firearms investigation team, which has had some great success."

A Serious Firearm Crime Investigation Section established in August has made 48 apprehensions, seized almost 200 firearms and searched 60 premises. Other prohibited items such as drugs have also been seized.

Firearms Prohibition Orders are also active for 81 people and pending for another 37.

The orders are issued against people with a history of serious criminal activity or a propensity for violence in a bid to curb the use of firearms.

They give police significant powers to stop and search a person or vehicle, as well as the power to enter and search premises without a warrant.

Meanwhile, police have been told South Australia Government expects more violent crime charges and prosecutions this year after being handed a suite of new anti-gun, anti-gang and anti-violence laws.

Commenting on the murder - the 13th shooting in SA since a teenager was shot dead at Warradale on New Year's Eve - Attorney-General John Rau said he was confident police would deliver results.

"In terms of execution of the law it (the ball) is in their (the police) court but with total support from me and total support from the government.

"We are not saying it is all your fault, we are saying we have confidence in the police and we are confident you will use the tools we have given you.

"I am confident they are going to start getting some results. They now have tools available to them that they have not had, like the organised crime offences, the better control on firearms, carrying knives, and searching for weapons."

Asked what changes South Australians could expect by the end of the year, Mr Rau said: "I would expect that some of the new laws would start to be demonstrated in terms of prosecutions".

"It would be a brave person that would predict the shootings would stop completely but I'm sure the people involved in shootings are going to be thinking more carefully about what they are doing," he said.

"I can tell you this with absolute certainty, the new police commissioner is giving every attention to using every tool he has in his tool kit ... "

He said he was confident that in the course of the year there will be clear evidence that police were putting pressure on criminals.

Mr Rau said police would have their first chance to use many new powers this year. The laws that had only recently been passed by Parliament allow them to:

PROSECUTE people who were inadvertently helping a crime gang.

OFFER sentence reductions to criminals who dob in their mates, the so-called "super-grass" law.

USE metal detectors near licensed venues to search for concealed weapons.

STOP children buying knives.

TRACK and record more people without court approval.

FINGERPRINT more people on the street using mobile scanners.

There would also be renewed attempts to ban outlaw gangs, after changes to laws because of a High Court challenge.

In a written response, Police Commissioner Gary Burns agreed police had been given "extensive legislative tools by the Government to help curb both organised crime and gun violence".

"However, the battle to remove illegal weapons from our community is constant and difficult, with no one easy measure to solve this complex issue," he said.

The victim of yesterday's shooting was found in the driveway of the Big Bucket Car Wash in Parafield, near Bunnings Warehouse on Lawrence Hargrave Way. about 6.40am yesterday.

He was treated by paramedics for gunshot wounds to the forehead and hip, an SA Ambulance spokeswoman said. The man was rushed to the Royal Adelaide Hospital with critical injuries but died shortly after arrival.

A burnt-out silver Kia sedan was found on Myall Boulevard, Salisbury, about 30 minutes later but police investigations ruled out any links with the shooting.

A police spokesman said the shooting did not appear to be linked to bikie gangs.
