According to some commentators (see here and here), Putin is to blame for the bloody events in Kiev over recent days since "he muscled Ukraine into backing out of trade talks with the E.U. and has been pressuring Ukranian president Viktor Yanukovych to crack down on his own people". The burning tyres - recalling the violent protests in Kiev - are arranged in the shape of the Olympic rings, an obvious reference to the winter Olympics in Sochi. Putin was keen for the Sochi Olympics to be his legacy, but it now looks like that will be overshadowed by events in Ukraine.
Someone's legacy is something that they have achieved that continues to exist after they stop working or die. • Perhaps her most important legacy was her programme of educational reform.
