In live action and again on video replay, it was painfully obvious to the Dynamo on Saturday that their dropped points could have been retained if the linesman correctly raised his flag.
Instead, he left it at his side and an equalizing goal by the LA Galaxy in the fourth minute of second-half added time was allowed to stand.
The Dynamo left the StubHub Center with a 2-2 draw and the bitter taste of a result they felt was taken from them.
Coach Wilmer Cabrera, however, said the linesman is not to blame.
