Is there a law against owning someone else's DNA without their consent/knowledge ? I've googled it but I'm a bit confused. It says here that in California the police can compile a database of DNA without people being convicted or charged. It also seems like the 4th Amendment could be used to secure your DNA but the ruling mentioned there states
"your DNA can be taken and entered into a national database if you are ever arrested, rightly or wrongly, and for whatever reason."
Otherwise, not much has come up aside from third-party gene testers. The results on this site seem to say (at least, to my uneducated eye) that you can't "protect" your DNA by copyright or patent if you abandon it (cuz trash is public property).
Does that mean that police can go through your trash once it's out of your curtilage ? This site says you can file a motion to suppress any trash evidence (if within your right of privacy ?) but is there a case where the police can't get a warrant to obtain your DNA directly but can instead wait for your trash and then get it from there ? Or is every case where a warrant isn't obtainable also a case where trash evidence isn't allowed ?
And what about anyone ? I can think of a few queasy things someone can do with your DNA like finding out details about you that you don't want them to know. In 2006, the UK made it illegal to sequence another person's DNA without permission. But it says here that it should be a felony theft in USA but isn't ? Yet ? Are there any other countries like the UK ? Does it instead matter much more what I do with the DNA I collect or is simply intentionally owning it enough to constitute a crime ? Let's say I follow someone into a barber shop and leave with some clippings of their hair, am I doing something illegal ? I'd expect this to vary from state to state, right ?
