They will say it is to hard to figure out who has had new training and who hasn’t. Due to this all renewals after (date they finally have a requirement) will need the new training to renew.
Just my opinion.
It's six years until renewal.
I think there is a better-than-even chance this law will change drastically before six years have passed. I think it's likely those changes will come as the result of a SCOTUS ruling or two, but there could be other reasons too. Either way, I don't think it's a done deal that anyone will ever actually have to cross this mythical training hurdle.
