Late Game Fouling

[Spence]

How much leeway do we give teams who are fouling to stop the clock late in a game? What has to happen before you call an intentional foul?

I had a game last week where the defender whiffed on the steal attempt/foul attempt with his left hand and then in the same motion grabbed the dribbler's jersey with his right hand as the dribbler. Intentional? What about the "arms around the dribbler" foul?
