NSW Premier Barry O'Farrell rejected the opposition's calls for tougher laws to prevent shootings saying extra powers and 250 additional officers had been given to police at the request of the commissioner.
"I'll continue to support the police who've done a significant job," Mr O'Farrell told reporters in Sydney on Saturday.
"One thousand arrests, extra police, additional powers, all to try and stop this targeted villain-on-villain shooting."

Mr O'Farrell also called on Prime Minister Julia Gillard to stop cutting staff and funds from the Customs department.
He said less than 10 per cent of air and sea cargo was inspected by Customs, making it easy for guns to make their way onto Sydney streets.
"It's no coincidence that last year NSW Police intercepted 220 Glock pistols being posted to this state.
"The quicker police are taking guns off the streets of western Sydney, the quicker they are coming back into the country because of the federal government's Customs cuts."
Mr O'Farrell that laws for the outlawing of gangs could now be applied - after the failure of a High Court challenge to them in Queensland - and would be discussed at the upcoming Council of Australian Governments meeting in April.
