BBT Center is at the following address: 2555 NW 136th Ave, Sunrise, FL 33323
Sunrise FL has an event permit form (“Special Event Permit Form”):

There’s no online access to the forms, but an anon could easily call Sunrise and ask them for the date the form was submitted. Form itself states that it’s required 30 days in advance, so it would have been notable in that it was processed as an exemption to that rule.
IMHO this is a red herring, but can't hurt to rule it out.
