When wee UD studied at the Medill School of Journalism, we often discussed the qualities of a good lead sentence; in particular, you want to pack a lot of information in without creating a run-on feel to the thing.
The AP writer who had to pack all of the repulsive behavior at New Mexico State into her lead had quite a task, but she acquitted herself well, finding a place in one sentence for the guns thing AND the cock-grabbing thing. Actual shooters (of guns) among team members appear a little farther down in the article. When there’s this much material, you have to be selective.
