Capitol Police were unprepared for the Jan. 6 demonstration despite warnings. But now they are right there on duty to stop children’s choir in midst of singing National Anthem. Still, look on the bright side: They didn’t go Ashley Babbitt on the kids. Now maybe they will indict Trump for conspiracy to sing Anthem. Isn’t that what is meant by a witness “singing”? When our justice system becomes a laughingstock, it’s time to weep.
