Before deciding priorities between SARs and personal privacy in the great outdoors, one has to ask oneself what is his/her personal motivation for the need for privacy in public places!
Those who abide by the laws of the land and are guided by a moral compass I suspect would have less objection and would be most in favor of SARs and proactive monitoring of possible terrorists acts etc.
But any government that covets this technology so as to have extensive control of society might be less inclined to allow the public to have unlimited access to such technology.
The USSR once had this problem under Lenin and Stalin.... wanting to see and hear everything so as to maintain and increase their control to the max...... being trousered apes incapable of trusting anyone including themselves.
