Since he is a wicked person, we do not want him as part of the Jewish community. (Meam Lo'ez, Vol. 7, Mishpatim, Exodus 21:1 - Excommunication)

The Young Israel organization refused to follow the halachos specified in this seruv to ostracize and shun the charlatan "rabbi". In fact, they committed FORGERY and PERJURY to hide the seruv from Klal Yisrael!

The eruv in West Las Vegas was formed with the full knowledge Young Israel will not allow the widow (and others the so-called rabbi publicly expressed his hatred toward) into the shul to partake of the ochel, the food component of the eruv. Halacha considers the rabbi of that Young Israel a heretic for his actions and his public distortions of the Torah and all halachos of excommunication (Yoreh Deah 334) apply to him. For these reasons stated in the Shulchan Aruch Orech Chaim that were deliberately contravened in these sections 366:5, 385, 394:3 (click here then scroll to view)  the eruv is pasul!
The Las Vegas Kollel's say-so to the contrary is worthless since they cannot give valid halachic explanations or reasons.

Travelers to Nevada must avoid carrying on Shabbos in the areas surrounding the Young Israel of Las Vegas!

6. And Moses said to Aaron and to Eleazar and to Ithamar, his sons, "Do not leave your heads unshorn, and do not rend your garments, so that you shall not die, and lest He be angry with the entire community, but your brothers, the entire house of Israel, shall bewail the conflagration that the Lord has burned.

ו.   וַיֹּאמֶר משֶׁה אֶל אַהֲרֹן וּלְאֶלְעָזָר וּלְאִיתָמָר | בָּנָיו רָאשֵׁיכֶם אַל תִּפְרָעוּ | וּבִגְדֵיכֶם לֹא תִפְרֹמוּ וְלֹא תָמֻתוּ וְעַל כָּלהָעֵדָה יִקְצֹף וַאֲחֵיכֶם כָּל בֵּית יִשְׂרָאֵליִבְכּוּ אֶת הַשְּׂרֵפָה אֲשֶׁר שָׂרַף יְהֹוָה

Rashi:

so that you shall not die: But if you do so [and leave your heads unshorn and rend your garments], you will die. — [Torath Kohanim 10:31]		ולא תמתו: הא אם תעשו כן תמותו:

Why would Hashem be angry with the entire community if Aaron and his surviving sons were to disregard His instructions?

Rav [Shimon] Schwab (zt'l) on Yeshayahu (Artscroll)  brings a reference on page 14 from Sefer Yehoshua, Perek 7 where the defeat at Ai cost some 36 Jewish lives :

"Achan's close circle of family and friends who knew about the violation did not condemn him for it; they didn't ostracize or shun him. So the entire nation was held responsible."

---

According to Rambam (Hil. Taanis 1:1-3), it is a positive commandment of the Torah for every individual to cry out and search his ways at a time of national calamity, for G-d visits calamities upon Israel to inspire each Jew to repent for his misdeeds. If someone fails to recognize that tragedies occur through an act of G-d rather [than] through happenstance, he is considered cruel, because he will not be motivated to improve his behavior. as a result, G-d will beset Israel with more troubles, until all are motivated to change their ways. (Footnote from Artscroll 1982 edition  Sefer Yehoshua, Perek 7  )

If the disregard for the sin of Achan by "Achan's close circle of family and friends who knew about the violation " (Rav Shimon Schwab, ztl) brought about the tragedy at the Battle of Ai then it stands to reason that the suppression of the excommunication of Yitzchak Wyne by his close circle of "rabbinic" and Young Israel colleagues very likely is bringing similar Biblical responses where Hashem is trying to reach the conscience of the community leaders as He did Yehoshua. 

Achan ben Carmi defied a cherem on the booty of Jericho and the result was national mourning for some 36 lives! Mr. Wyne oppressed a widow and was placed in  cherem  as result but his close circle keeps it hidden from the general community! They let the locals and travelers think it is a YOUNG ISRAEL like those led by Rabbi Menachem Gettinger zt'l, Rav Yehudah Leib Isbee zt'l, Rav Schulem Rubin zt'l, et al.

IT IS NOT DESERVING TO USE THE NAME YOUNG ISRAEL and it is NOT a branch of AISH HaTORAH!

Las Vegas is definitely no longer an affiliate of Aish HaTorah on any level, and should have removed the name from their stationery etc. They have been asked to do so and we will follow up on this. Thank you very much for bringing the matter to our attention.

This status has not changed in 8 years!  Young Israel Aish of Las Vegas is NOT affiliated with Aish HaTorah despite their use of the name and logos.
