VICTORIA — Police in British Columbia should continue using the Taser as a weapon of force despite four deaths, but better training is required, says a report released Wednesday.

"Our analysis of the field usages and the medical literature suggests appropriate use of the Taser presents an acceptable level of risk to subjects being controlled,'' concludes an interim report ordered by B.C. Police Complaints Commissioner Dirk Ryneveld.

But, while the B.C. Civil Liberties Association said the report was positive, the watchdog group said the technology is still evolving and must be monitored.

The report, written by the Victoria police chief, includes five recommendations for police across British Columbia.

They are:

• A standard provincewide police Taser training course.
• Mandatory reports of all Taser uses.
• Moves to new technology.
• Better training for officers with regards to drug abuse behaviour.
• Elimination of a police restraint method that involves handcuffing hands and ankles behind the back.

"We believe that more can be done to ensure uniformity of training across the province to provide enhanced levels of accountability and to decrease the risk to those groups most at risk from sudden and unexpected death associated to restraint, whether or not the Taser is used,'' said the report.

Ryneveld ordered the Taser use probe following reports of the June 23 death of Robert Bagnell of Vancouver.

Bagnell, who was high on cocaine and other drugs, was hit by the high-voltage charge of a police Taser in a Vancouver hotel room. He died at the scene.

Vancouver police waited a month before confirming one of its Tasers hit Bagnell.

Victoria police Chief Paul Battershill was appointed to lead the probe that included investigating the Bagnell case and reviewing the use of the Taser by police officers in British Columbia.

The interim report issued Wednesday only examined Taser use in British Columbia. Four people have died in B.C. in the past 15 months in circumstances where police used a Taser.

Each incident, including Bagnell's death, is the subject of a coroner's inquest, all of which are expected to be completed in six to eight months.

The four B.C. cases involved individuals suffering from excited delirium, a condition known to be caused by psychiatric illness or overuse of street drugs, primarily methamphetamine and cocaine.<

At a press conference in Victoria, Battershill said police can expect to encounter people in states of excited delirium more frequently as drug use increases.

The report recommended the creation of a standard police course on interpreting signs of excited delirium to all police officers, new recruits and current members.

"That appears to be under-recognized in both the police and medical communities right,'' Battershill said.

Training in Taser use must be standardized across British Columbia because inconsistencies between police departments were discovered as were reporting deficiencies, he said.

All Taser uses must be reported, Battershill said.

Police were also advised to switch to new Taser weapons that emit lower levels of electricity, but provide better control and information storage.

B.C. Civil Liberties Association spokesman Murray Mollard said the only negative aspect to the recomendations is that they should have been made five years ago.

"They're late in coming but now that they're here, it's a good thing,'' He said. "This is an interim report so we're going to hear more. The technology is new enough that they're going to have to keep doing this.''

And, Mollard added, evidence out there doesn't support removing Tasers.

"We've always said this is an important addition to the use of force spectrum but it must be used appropriately,'' Mollard said.

At least six people have died in Canada after being shocked by Tasers.

The devices fire two barbs attached to a wire that deliver a 50,000-volt shock on contact for up to five seconds. The weapon is meant to immobilize aggressors by shocking their muscles.

Police like the Taser because it offers a less than lethal option for dealing with dangerous and unstable people. But critics say the weapon is sometimes lethal.

Amnesty International has said the weapon should be banned until more tests are done to determine its safety. The human rights group says the guns can be deadly when someone is in a weakened state because of heart problems or drug use.

About 50 people have died after being shot with Tasers in North America, most in the U.S.

The B.C. report examined 4,500 Taser uses across North America and Europe, said Victoria Police Insp. Bill Naughton.

Of the 4,500 uses, four deaths were reported, he said. The B.C. deaths were not part of the current probe because they are still subject to a coroner's investigation, said Naughton.

He said the Taser is effective 94 per cent of the time.

Naughton said the report would have recommended banning Taser use if it found the risks outweighed the advantages.

"I don't think we took anything off the table,'' he said. "We would have banned it.''

Ryneveld said he will give a copy of the interim report to Rich Coleman, B.C.'s Solicitor General and the minister responsible for policing in British Columbia.
