> The U.S. Supreme Court has held that the Constitution gives you no privacy rights over your garbage, but individual state constitutions can offer more stringent privacy rights. Warrantless trash searches by police are not legal in Vermont and New Jersey.
Usually if trash is put on the street by the curb, it is not on your private property and can be taken and inspected. There would have to make an explicit law I think to protect it. But what if the police follow the trash truck to the dump, does it extend there as well?
That's why things should be shredded and some intelligence agencies have their own incinerators and so on.
In many US states streets were never formally deeded to the municipality when the lots were platted, and there's a long standing legal principle that the lot owner has a fee-simple interest to the middle of the street. (Washington included, not sure about Oregon) ie, it's not public property, it's private property with an easement dedicated to the public.
Right if I drop my bag on the ground it should immediately be free for all and available for police search. But trash is considered "abandoned".
I didn't know about easement but it makes sense thanks for pointing that out.
