The union appears to be in on it unless I read that incorrectly.
No- they are saying follow regulations but contact them if they need legal representation:
” The Uniformed Fire Officers Association sent out a message to its members on Saturday warning them of the directive and that the department is in “possession of video footage of the event.”
“As part of this discussion, questions may be asked to specific UFOA members over their actions or their recollections,” the message said.
The union advised members to follow FDNY regulations but to contact the UFOA for legal representation if they feel they are the subject of an investigation.
