This in from BHB contributor Weegee, responding to a reader’s comment:
If you’re referring to the modern fire apparatus that was in front of 195 Montague, that had nothing to do with the set-in-1921 scene being filmed in Borough Hall. There was a very real incident in which two workers sustained serious electric shocks and a small fire broke out while they were installing a high voltage panel on an upper floor of that building. Both went to the burn unit on Staten Island in critical condition.
