Dude, you are reading things into the amendment that was never intended. The abuses you are talking about are covered in the 4th amendment. I’m glad you are not a Supreme Court Justice (At least I hope you’re not) because you would be reading things into the law instead of what it plainly says.
The 3rd amendment is what it says it is. The government is not allowed to quarter soldiers in people’s homes during peacetime. Yet, you read in a distinction in the 4th amendment concerning overt and covert searches (only overt searches are covered in the 4th amendment according to you). That distinction is not there.
I guess we’ll just have to agree to disagree. I think I’m right and you think I’m wrong. So be it.
