Is There a Difference Between Imam and Imam?

I've been very strict that anybody we get has to be a person who knows his de jweet and no mistakes in the jweet. Even if one half is mistaken he cannot be the imam unless the whole community is the same then they can choose somebody of that level. The finer details of fiqa and the other medah will have their priority so what trumps what when it comes to being the imam? We need to rethink this through maybe at some societies and times when there were a lot of negativity within valleys maybe we understand now these things are changing.
