So, there's more to this....of course.
This could be coincidental, but the statue was taken down on the 3. of April. On the 7. of April, Putin signed into law a decree criminalising destruction or defacement of Russian military/war memorials and graves in foreign countries, punishable by up to 5 years in prison.
On the 10. of April, Russia started a criminal probe into the statue's removal.
I kid you not.
One of the council members under threat is the magistrate of Prague 6 (Pirate Party), and one of the others has been secreted away under police guard, though all three are under police protection.
The statue is in storage.
Fyi, Konev led the Warsaw Pact suppression of the Hungarian Revolution in 1956, or whatever year it was and was also involved in the suppression of the Prague Spring.
So, anyway, why his statue was still there in 2020 is the real subject for criminal investigation.
