Anti-Seperatist Operation in Kharkiv

The story is that between dozens and hundreds of Pro-Russian separatists seized government buildings in Eastern cities. (These are cities of about a million.)

Similar amounts of police allowed them to do this with no resistance. They are probably compromised or else trying to create some job security by allowing crises.

Since then, Ukraine reinforced eastern police with units from other parts of the country and also had special units like the one involved here do SWAT-style raids.
