The former president of the National Association of the Deaf, Chris Wagner, who has previously worked in Manatee County, said the debacle was an insult to the deaf community. When Greene began signing words like "pizza", "monster" and "bear", along with other gibberish during an emergency evacuation order - those who are hard of hearing were livid.
McCarthy told BuzzFeed News that when she spoke to emergency officials, she also offered to provide an interpreter to the county so the deaf community there could also stay informed during broadcast briefings during Hurricane Irma. County officials tell WPTV they were "in a pinch" to find a qualified professional interpreter for the briefing, so they asked an employee.
They added he was not familiar with the language used by the officials.
County leaders have faced the brunt of the criticism for failing to organise an interpreter despite days of weather warnings.
"It was horribly unnerving for me to watch that, knowing I could provide a qualified, certified interpreter", McCarthy said, obviously frustrated that her company wasn't called in.
Wagner said Greene also fell foul of basic good practice for interpreters by wearing a bright yellow shirt, thereby making his hands less visible to deaf viewers.
While getting ready to prep the public with "crucial" information leading up to Hurricane Irma's impending arrival, Manatee County leaders found themselves without a deaf interpreter.
Greene, who uses the sign language to communicate with his brother, signed words unrelated to what the speaker was saying at the news conference, it said.
"He can't expect to communicate something he doesn't know", his father said.
Critics said Manatee County put people in danger when they put Greene up to the task.
"They said yes, for the next morning at 9:30 am", she said.
The deaf community is demanding an apology from the county for the blunder, according to WFLA.
