I agree. I *hope* that the "standing in front" tactic was done out of ignorance and that the resulting crash wasn't expected. (I know, that sounds ridiculous from those of us who know from peletons and physics.) Cops don't swerve in front of speeders to get 'em to stop - and that's just one speeder, not a large group. Seems it would have been far, far more efficient to follow 'em and get out the ticket book.
