Question

About half a year ago I asked the Rabbi a question here on the site, and the Rabbi answered me that it was a question suited to Adar and maybe then he would answer it.
Unfortunately I wasn’t able to find that question, so I’ll repeat it briefly, and I’d be glad if the honorable Rabbi would answer.
Of course, the Rabbi’s decision about when to answer is legitimate; the Rabbi doesn’t owe me anything. But if the Rabbi thinks this is, Heaven forbid, trolling and therefore chose to answer only in Adar, then I hereby inform you that there is of course no concern of trolling here.

And now to the matter itself:
A respected cantor in the community arrived at the Kinneret, and instead of stepping out and relieving himself in an appropriate place, he did so in the Kinneret where everyone bathes.
Afterward he loudly announced what he had done, and also dipped his hands in the water of the Kinneret after urinating there, put the child’s swim ring on his head, and recited the Asher Yatzar blessing loudly and in cantorial style.
It didn’t bother him that the public around him—some laughed, some were just embarrassed, some were disgusted, etc.

And now to my halakhic questions, in my humble opinion.
1. Is someone who urinates in the Kinneret fit to be a cantor in a respected community? (And he loudly announced what he had done.)
2. Does dipping his hands in water into which he had just urinated suffice for the blessing?
3. Is a swim ring suitable attire for a blessing?
4. Aside from the Jewish law, does the Rabbi have a moral comment on this behavior? (The cantor, unfortunately, peeks at this site.)

I would be glad for the honorable Rabbi’s answers.
And have a good month.
