Who's foul?

[ZEBRA]

Communicating information to your
partner is invaluable. This is what works
for me:
TWEEEET(whistle), arm raised, close in on
offender, call out number and color of
offender, signal for 2 shots or spot for
throw in. I don't listen to anything else
until I have finished this, unless my partner
and I have a double whistle. If that is the case
we get together and go with what I got
(just Kidding)
