It's attitudes like yours that have led to loss of freedom in this country. "Not doing anything wrong" is defined by this tyrannical federal government. Am I "doing anything wrong" if I am growing a certain plant that happens to look like hemp (there are many)? With a drone looking at my garden, that very well may earn me a visit from a DEA SWAT team.
Was Randy Weaver "doing anything wrong" when his rifle stock was 1/4" too short? Had they had drones then, they might have just dropped a Hellfire on his house instead of having the FBI sniper murder his pregnant wife and his son.
Saying "if youre not doing anything wrong, you have nothing to worry about" and just letting this government do whatever it wants will lead to people being murdered. It always has, and always will. Government will take every power they can get, and want more.
I think the poster was being sarcastic.
