From Wikipedia
https://orthodoxwiki.org/Nestorianism
Nestorianism is a Christological heresy which originated in the Church in the 5th century out of an attempt to rationally explain and understand the incarnation of the divine Logos, the Second Person of the Holy Trinity as the man Jesus Christ. Nestorianism teaches that the human and divine essences of Christ are separate and that there are two persons, the man Jesus Christ and the divine Logos, which dwelt in the man. Thus, Nestorians reject such terminology as "God suffered" or "God was crucified", because they believe that the man Jesus Christ suffered. Likewise, they reject the term Theotokos (Giver of birth to God) for the Virgin Mary, using instead the term Christotokos (giver of birth to Christ) or Anthropotokos (giver of birth to a man).
Christology
"Usually, the Assyrian Church of the East denies that it teaches Nestorianism. On November 11, 1994 Mar Dinkha IV and Pope John Paul II signed a "Common Christological Declaration" which affirmed that Catholics and Assyrians share a union in their understanding of the Son of God. [1] In 1997 the Assyrian Church halted anathemas of other churches in its liturgy.
Nevertheless, the Assyrian Church of the East has recognized Theodore of Mopsuestia as a saint, whose Christology was condemned repeatedly as Nestorian by the Orthodox Church. "
It was a fairly easy transition from Nestorian belief to Islam, which facilitated the conversion of conquered Byzantium Christian areas--like Syria--to Islam.
In other words, there isn’t evidence they were going to lynch the guy, not even so much as a rope, but the police “feared” they would, in much the same way the FBI fears Christian nationalists in the US.
In a way government will, by always running to the defense of Islamists, and by failing to prosecute wrongdoers, eventually cause the mainstream people to resort to vigilantism as the only means of ontaining justice.
