They have to flag everything....

It's a judgement call so they could never make everyone happy.... they can piss everyone off however, and at least that's unanimous.

Reminds me of the 'hands on the back'.... stupidest ruling ever... but it gives the officials an out. "That wasn't interference!" - - "Yes it was, see on the replay, his pinky finger touched the fabric of his jersey" - "Oh yeah, you're right, it's PI". - JamesJM
