I don't think so. Other than a brief detention, the police in general cannot arrest anyone without having sufficient probably cause to persuade a judge or magistrate to issue an arrest warrant. It appears that ALL the Florida law is trying to do is prevent the police from jumping the gun (pardon the expression) and arresting someone before they have established probably cause.
I don't see that as a bad thing ...
I don't see this as a bad thing either.
I think a point to remember is just cause LE doesn't find sufficient evidence for an arrest in the initial interview, DOES NOT mean the investigation is over and they won't find sufficient evidence for an arrest at a later date.
