Australia - The number of warrants allowing police to spy on suspected criminals and allegedly corrupt police and public servants increased by 67 per cent over the past year.
But the number of arrests and charges arising from the bugging of houses and cars, and the tracking of cars and computers, remained low, at about one for every 10 device warrants issued.
More than 860 warrants were issued by NSW Supreme Court judges last financial year, triggering the installation of more than 2100 surveillance devices including listening devices, hidden cameras, tracking devices and technology to monitor emails.
The figures do not include the use of other surveillance devices, such as telephone intercepts. (more)
