UAV's Used To Spy.....

Yeah, that's just what we need: people concocting DIY heat-seeking missiles and shooting them into skies full of airliners.

I have a feeling that the expense of such a scheme would prohibit all but the most successful criminals from inventorying very many of them.

The criminal elements with the most to lose already have them.

From a terror perspective, there is already a target rich arena in the sky with manned aircraft.

Fortunately, the technology and skill to design, build, and execute such a device is very challenging.

They are small, and can fly high enough, to be undetectable without sophisticated surveillance ....The missiles alone are about $2 mil each....

Would not be that hard.

Have at it. I am sure the US military would be very interested in such a device (if they don't already have one).

I recommend you to be the first to shoot down a law enforcement UAV. It's your idea, you defininitely should try it first.

Do you shoot at "unmanned" police cars when they are parked in your neigborhood with the dash cam left running?

ha ha - that was funny!
