The Federal program's aim is to determine if blood draws by cops can be an effective tool against drunk drivers and aid in their prosecution.
They will draw blood of any suspected drunk driver who refuses a breath test. They'll use force if they need to, such as getting help from another officer to pin down a suspect and potentially strap them down, Watson said.

The article then goes on to describe how officers in Texas and Idaho are training to withdraw blood from "suspects" as a replacement for the standard breathalyzer test, primarily because police can't make anyone breathe into a tube but apparently, in the "land of the free," they can forcibly hold someone down and jab a needle into their arm and take their blood, "a practice that's been upheld by Idaho's Supreme Court and the U.S. Supreme Court," according to the APreport.
