I was told all the cameras had been confiscated.

Not at all. It was assumed you'd understand that attempting to PREVENT the other team from scoring is also expected. Stalling does exactly that.

I Know That We're Getting Killed, But Please Press Us ...
 

During my dark days as a middle school basketball coach, I actually asked a "Powerhouse" coach to put his press back on for a few minutes in the second half so that we could work on our press break. He did. We still had trouble breaking the press, and he took it off.

Also, I informed both the parents, and the officials, about my request

Way back when I was a freshman in HS we had this exact situation. We were beating the dickens out of the team we were playing. This was back before the running clock rules became prominent. 4th quarter and we were up 70 something to not much. At one point in time the other team inbounded the ball straight one of my teammates and he shot a uncontested layup. And they did it again. And again. Soon all of us wanted a piece of that action and were like kids in a candy store. running toward that end of the court. After about four five times they threw a long pass and they scored an uncontested layup because we were all on the other end. I think the score was 94 to 30 something. Although I didn't pay attention to that stuff back then I don't remember there being any forfeit discussion or the like from the officials.
