Crowd (spectator) Technical

[Cleefy]

I was umpiring a Under 10 girls grand final, (under fiba rules), and I called a blocking foul on a girl, for stepping sideways, into the dribbler, with her legs wider then her shoulders (cylinder principal). At which point, the girls Mother, and two brothers start screaming down my throat. A few curse words were thrown in, before the big, 'bomb' in my opinion. The mother stood up, and said "She wasn't even moving, and her legs weren't that wide, get your eyes checked, you silly old sod". At this point, I blew my fox mini, and teched the bench of that team - although I hadn't given a previous warning. At my association, we are allowed to tech spectators for disputing decisions.

I'm after your opinion on the matter,

Thanks. Cleefy.
