The scare campaign is without foundation, things depicted on this obviously faked video just can't happen in Australia, the gun laws would stop it because criminals and terrorists can't get guns without a licence.

Is Mise,
Yep, firearms laws will stop most from having fun, but some smarty will develop a way to override the controls and bring it down for their own use.

I have emergency & general aviation helicopters flying over my place a few times a day, any of then, with even reasonable cameras could film any of my activities, if my activities were ever worth filming. As this is highly unlikely to be the case, I have no fear of drones, & neither should any law abiding citizen.

Hell just a slightly better version of Google earth photos, [readily available to authorities], would tell them all they need to know about anyone of interest.

Talk about storm in a teacup.

"the gun laws would stop it because criminals and terrorists can't get guns without a licence"

LOL, dry wit. A sarcasm alert is needed for the hoplophobic gun control nuts who believe the 'gun control' spin contrary to the evidence before them.

The criminal gangs who manufacture and deal in illicit drugs and are responsible for almost all of Australia's violent crime and standover tactics already have heaps of video cameras and other surveillance surprises including man traps for anyone with cause to wonder what they are up to. It is only fair that the authorities use a drone in response to detect criminal activity and save lives in the process.

The concern is about what private drones may be uused for and whilst the law abiding should have nothing to fear, conversely they should not be subject to spying.

"They prefer the term Unmanned Aerial Vehicle to the more sinister sounding ''drone''. But the Metropolitan Fire Brigade has announced it will from now on use the high-tech flying objects, dubbed CQ1 and CQ2, to monitor fires and major incidents.

In a 12-month pilot, two remote controlled, quad-rotor miniature aircraft armed with cameras will be be sent to take bird's-eye footage of emergency incidents across Melbourne. They will transmit real-time images to incident controllers at emergency scenes."

Unfortunately they can also be used to start fires.

Controls will be needed, if a Zimmerstutzen needs to be licenced because of the perceived threat to society then also these drones need to be regulated as they pose a far greater threat.

onthebeach,
More rules and regulations.
We need less control and more freedoms.
