Except that his legitimacy as the leader was put in doubt by his unconstitutional changes to the UKR Constitution, reversal of the EU cooperation legislation, and then finally ordering the Police to use disproportionatly lethal force against peaceful protestors (and, no, it wasn't self defence). And then there's the evidence of his skimming the Public Purse when in office
Lets see
Govts changing legislation...............happens all the time in every country
Unconstitutional Changes to Constitution.............you are saying Unconstitutional but sorry can I see the legals involved
Reversal of EU Cooperation legislation..........again Govts change legislation or interpret it to suit themselves, Obama on US constitution, UK Attorney General in saying Iraq war is ok, UK Govt in stating GCHQ recording everybody is ok
Police using Lethal force............again happens all the time across EU as police are allowed use Lethal force, remember in UK not a single policeman has been jailed for shooting someone
Evidence of skimming public purse............in which case produce the evidence that stands up in court, of course the Billionaire now in control of Ukraine will provide all the data, like the Interim President who destroyed all those records in 2005 as head of security.
