Do we really require a shliach tzibbur to be of sound levels of observance and morality? I’ve been in many, many minyanim in which someone they’ve never seen before walks in and asks to daven from the amud because of a yahretzeit. I’ve never seen the request refused on an ordinary weekday unless someone else was celebrating a yahretzeit. How did they even know the guy is Jewish at all, much less shomer Shabat?
