Do you want fotage of your 3 year old playing in an inflated pool in your back yard to end up on pedo.net because you didn't put a cammo net over your back yard?
Parrot drones are super fun, but it isn't hard to play with them responsibly.
More importantly, "think of the children" is a common justification for bad laws. Human minds tend to give too much weight to low-probability stories. Nobody freaks out about the thousands of children who die every year from car accidents, but if a technology has the potential to take pictures of children surreptitiously they call for bans.
Drones are just like cars: people are going to be harmed by them, but the benefits are almost certainly greater than the costs. And that's before you consider how many applications for drones that we haven't yet thought of.
Where does one acquire such an extreme level of paranoia? I mean, seriously...
Sure, your average joe nobody is not likely to be targeted, but as the cost to acquire aerial video goes from $x,xxx an hour for a helicopter, to $x/hr for a drone, it will be used far more widely. In the past, it was prohibitively expensive and time consuming to do surveillance work. Now a smart phone with 4G tied to a balloon can stream HD feeds.
In the past, you had a reasonable expectation of privacy in the curtilage of your home. If drones can take high resolution photos (and video) from the air, this becomes null and void. I personally would prefer we have laws to protect privacy instead being forced to completely enclose all outdoor pools or risk showing up on poolperv.com's drone feeds. (Per my reading, the Video Voyeurism Prevention Act of 2004 would not ban bathing suit video)
Of course it is admissible evidence when the police see you sell heroin on the street, it is a little different when that gets changed intro a drone that can watch entire neighborhoods from the air.
And when the police gets those rights, so will other people.
