Ask them or find the exception in the law. I can't find it. Here are the references in the Florida law. Find the hearsay criteria used to allow the hearsay.
90.801 Hearsay; definitions; exceptions. 90.802 Hearsay rule. 90.803 Hearsay exceptions; availability of declarant immaterial. 90.804 Hearsay exceptions; declarant unavailable.
