While slogging through the snow, slipping around and trying not to fall on the ice or sitting in gridlocked traffic reduced to one lane because of that upcoming snowbank, not to worry: We still have our newsy diversions.For instance: what's up with that Yale cop who observed Yale student Tahj Blow coming out of a campus library, followed him, raised his gun at him and ordered him onto the ground?Describing the event of last Saturday night to his father, Blow said he heard the officer speak into his shoulder-mounted radio: "I got him!"Then Blow heard the officer say: "Hey, turn around!" Blow did so.
