また、ひろゆき氏は「死刑囚を生かす治療をするのは『裁判をする為』とか言われますが、生き延びて証言する事で死刑が免れる証言が存在するか?というと今の裁判官の判断基準では死刑一択だな、、と。生かすなら状況証拠だけで死刑が決まる裁判システムを変えないと意味がないかな、、と」とも投稿していたが、米山氏は「これも誤りで、今回問題になった心神喪失が認められれば、今回の案件でも死刑を免れられます。また、実行行為、故意、因果関係、違法性阻却事由の不存在等の認定も必要で、状況証拠だけで死刑は決まりません」と訂正し、「余りに基礎的知識に欠いているのに、何故こんなに断定的に物を言えるのかと思います」とあきれた。
米山氏はひろゆき氏の一連の投稿に、「自らが知りもしない刑事手続きについて、何の根拠もなくこういう誤った情報を流し訂正もしない、ひろゆき氏は、本当に如何なものかと思います」と苦言を呈し、「TV局はこの様な人物を識者の様に持て囃すのは、TV局の社会的責任として、本当に止めるべきだと思います」とつづった。

ひろゆき氏と米山氏をめぐっては昨年11月、ビジネス動画メディア「ReHacQ-リハック-」のYouTubeチャンネルで討論する模様が配信され、米山氏が“論破王”の異名を持つひろゆき氏を論破したと話題になった。

Hiroyuki also commented, "People say that the treatment to keep death row inmates alive is 'for the sake of the trial,' but is there any testimony that would allow them to avoid the death penalty by surviving and testifying? But if there is a testimony that can be used to avoid the death penalty by surviving and testifying, then the death penalty is the only option under the current judges' standards of judgment," he said. If you want to keep him alive, you have to change the trial system in which the death penalty is decided by circumstantial evidence alone," Yoneyama also posted. In addition, the death penalty cannot be determined based on circumstantial evidence alone, as it requires a finding of the act of commission, intent, causal relationship, and the absence of grounds for the exclusion of illegality.
Yoneyama complained about Hiroyuki's series of posts, saying, "I really wonder what kind of person Hiroyuki is, who spreads false information about criminal procedures that he does not know about, without any evidence, and does not correct it, I really think TV stations should stop having such a person as an intellectual as a social responsibility of TV stations," he continued.

Last November, a debate between Hiroyuki and Yoneyama was broadcast on the YouTube channel of the business video media "ReHacQ," with Yoneyama claiming to be the "king of debunking. Yoneyama debunked Hiroyuki, who is known as the "king of debunking," in the debate.

立憲民主党米山隆一衆院議員(56)が25日、X(旧ツイッター)を更新。“因縁”の相手である「2ちゃんねる」開設者で元管理人の「ひろゆき」こと西村博之氏(47)のX投稿の誤りを指摘し、苦言を呈した。

ひろゆき氏は24日、36人が死亡した2019年7月の京都アニメーション放火殺人事件をめぐり、殺人罪などに問われた青葉真司被告(45)の裁判員裁判で、京都地裁の増田啓祐裁判長が死刑判決を言い渡したことについて言及した流れで、「『人を刑に定めることは裁判官やないとできん。』嘘です。日本は警察官が現行犯を射殺出来ます。現場の警察官が死刑を下す事を法的に国は許容してます」などと投稿。これに対し、弁護士でもある米山氏は「出来ません」と否定し、警察官職務執行法第7条を記した上で「要するに警察官が犯人を射殺しうるのは、あくまで正当防衛若しくは緊急避難等としてであって、死刑の執行としてではありません」と説明した。

On March 25, Ryuichi Yoneyama, 56, a member of the House of Representatives of the Democratic Party of Japan (DPJ), updated his X (formerly Twitter) page. He pointed out an error in the X post by Hiroyuki Nishimura (47), a.k.a. "Hiroyuki," the founder and former administrator of "2channel," with whom he has a "history" and complained bitterly about it.

Referring to the death sentence handed down by Kyoto District Court Judge Keisuke Masuda at the jury trial of Shinji Aoba, 45, who was accused of murder and other crimes in the July 2019 Kyoto animation arson and murder case that killed 36 people, Hiroyuki said on April 24, "You have to be a judge to sentence a person to death. You can't do it. It is a lie. In Japan, a police officer can shoot dead a criminal in the act. The government legally allows police officers on the scene to hand down the death penalty," he posted. In response, Yoneyama, who is also a lawyer, denied that it was possible, noting Article 7 of the Police Duties Execution Law and explaining, "In short, a police officer can shoot and kill a criminal only in self-defense or as an emergency evacuation, not as an execution of the death penalty.
