Opposition Leader Dr Keith Rowley says National Security Minister Jack Warner's proposal to use new technology to pinpoint the location of gunshots will not work.

Dr Rowley made the comment in an interview at his home in Glencoe with TV6 News which aired Saturday night.

"I see a lot of hope is now being put on, and somebody going to get a contract, to find out where bullets are fired from. That person is going to get quite rich. It is not going to work here because the fact that it works out there doesn't mean it's going to work here because the geography of our area is quite unique as compared to other cities," Dr Rowley said.

Warner said last week, the "technology is coming that will be able to identify will be able to identify where the (gun)shot went off, when and which house it came from."

He did not, however, say who would be awarded the contract to provide the system to law enforcement in Trinidad and Tobago or how much it would cost taxpayers.

TV6 reported last week that the technology Warner may have been referring to is known as a Shot Stopper.

It works by placing the Shot Stopper sensors in selected high crime areas, where they can detect numerous different data from a gunshot

Rowley said this would be better suited for cities in other parts of the world.

"And the areas where the crime is taking place is taking place you don't have parallel and cross streets you have alley ways, you have lanes, you have up hill and down d hill, and this triangulation that is required would work in laid out cities. But in Upper Scorpion, Upper Ridge Plane, Upper Laventille, it's not gonna work," Rowley said.

He further said: "But they will give some friend of theirs a big contract to do something like that, they'll get rich, they'll walk away and leave us with where they found it."

Rowley also weighed in on the Police Commissioner Dwayne Gibbs' 21st century policing initiative which the National Security Minister wants to replace with a new anti-crime plan.

Warner has said that he will not support any plan that closes down police stations of police posts.

The plan is meant to ensure more patrols.

Rowley said his constituency was the "guinea pig" for 21st century policing.

"They closed down two of our main police stations, Caranage and Four Roads, We do not think that brings any comfort to the people in the district and, in fact, the complaints are that we do not feel safer and we are not seeing any significant increase in the patrolling that should have replaced the static police stations," Rowley said.

He said it was supposed to be a pilot project and is awaiting the outcome.

But Rowley says  Warner's instant dismissal of the 21st century policing initiative without an analysis of whether it is actually working or not is questionable.

"This is not a matter of the Commissioner of Police doing something on his own, this is Cabinet policy. Twenty-first century policing was a policy of the Government of Trinidad and Tobago being carried out by the Commissioner of Police. So they cannot now come and put it on the Police Commissioner's shoulder," Rowley said.

The Police Commissioner continues to defend the 21st century policing initiative despite Minister Warner's promises to replace it with another anti-crime plan.
