@GossiTheDog the US Empire has a long history of using healthcare and health workers to infiltrate and cause direct harm to targeted communities.
They pretended to vaccinate for flu in Pakistan, and instead of doing that they instead just stole genetic info to supposedly track bin Laden, despite that not being at all how genetic tracking works.
You can't tell if somebody is near by based on the genetic information of a person you know is in an area.
Not to mention Tuskegee, Puerto Rico, etc.
