1. if you have a conversation with someone behind closed doors, it’s considered private; the government can’t listen in without first obtaining a warrant and making a showing of probable cause. But if you have a conversation in a public place where it can be overheard by others, it’s not protected… What this means is that the degree of protection individuals have in their privacy depends a great deal on the degree of protection they themselves expect and preserve. To the degree that we ourselves act in ways that give up our privacy, the law will follow and give us less protection from government intrusion.
