Passed subcommittee today by unanimous vote.
I'm so sorry I never followed up on this - I thought I had updated everywhere I posted.. ๐ณ
This bill died in Committee - so for now, no journal requirement in Florida. We'll see if it's resurrected next year.
In the meantime, my personal opinion is it's still a good idea to keep one. You never know how good or bad your memory is until you need it - and a journal entry is more reliable than anything. Not to mention it's your only proof that the person appeared before you and was properly identified.
