1. The Iranian youth did not stop their protests after the killings by the paramilitaries;
2. The Iranian regime did not use thugs employed by prominent business owners to do the killing and instead used paramilitaries akin to the NKR forces brought in by the Armenian regime;
3. The Armenian regime did not manage to degrade the protesters by coercing false confessions and broadcasting them.
But overall, the tactics are the same. Authoritarian regimes function with pretty much the same scenario wherever you look.
