They don’t pull over other police cars, though....
The road blocks ironically brought attention to the more pertinent issue of the 3rd party’s involvement with the NHSA, and what the NHSA is hoping to accomplish the DNA data. Too bad this wasn’t the focus of the thread.
Were the tags recorded and associated with the samples? Doubtful.
Could the road blocks have been replaced with unavoidable signs offering 3x times the amount of money given no need for street cops? Yes.
Would folks in this economy voluntary donate for 3x the $$$? Definitely.
If there were no road blocks, would the DNA sampling have made the news? Probably not.
Did the road blocks turn off potential volunteers. Definitely.
There’s room for conspiracy concerns, but the cop, tags, road block angle is off target.
