First of all she did not crossed the line with her feet or body or hit anybody, Felix bumped into her with her right arm but she had baton in left arm and still made few steps before dropping it. One could argue that it probably made no real difference and that is Felix who actually run into outstretched arm of the brazilian runner. Anyway, no matter the rules I have doubt that any other countries protest would have been effective.
Watch video reply...Brazilians arm is in the way but she did not do it on purpose, heck american is behind her, she did not even see her. Contrary Felix had her in her sight and had all possibilities to avoid her.
