I understand, it is a tool. And how a tool is used, defines it.
I use and carry lock-picks as part of my job. They are perfectly legal, as long as they are used in a legal manner. They are NOT " burglar tools" unless they are used in that manner. They are a tool, nothing more.
The problem I see, is our laws have not kept up with our tech, and as long as there is no law against it, it is legal. (No, I don't want more laws, most of our new "Laws", don't fall in line with " the land of the free, and home of the brave" now.)
And as long as it is "legal" to harass, destroy, invade, and snoop, in a manner that would get you shot, buried, or jailed on foot, but by air is some sort of " journalism", I will oppose them.
Not because I find them useless for good purposes, but because so far they have been mostly used for bad purposes. There has been a GREAT deal of abuse, so far, even by law enforcement, using drones to spy where they could not get a warrent. (Having the ability, does not convey the Rightt, yet the law does not forbid)
Since it is only a tool, yet a tool that has been used for much damage, I fill continue to oppose them. And as the tool most utilized by those groups that spend their lives making our's hell and doing their best to destroy our hunting legacy and heritage, I would not oppose their being banned entirely.
I fully believe, that immoral, and illegal drone usage will lead to killings. Some by angry fathers of young daughters, some by law enforcement, as homeowners defend themselves from illegal warrantless searches. A man's home is his castle, and in the time of castles, spies were put to death without ceremony.
A drone is only a tool, but so is a gun. Point it in the wrong direction, and there will be consequences.
The only real difference between a good tracker and a bad tracker is observation. All the same data is present for both. The rest is understanding what you are seeing.
