The whole bit about the perpetrators fleeing to the Ukrainian border I actually kinda believe.
Not because ukraine was involved but its got to be the only border anyone can get through at the moment within easy distance from moscow.
Everyone else has shut their borders
Edit: yes I know its a war zone yes I know its monitored.
I also believe that you can never fully secure a land border there will always be holes AND the scum who shoot up a concert hall are not exactly at the top of the IQ range when it comes to escape plans.
So h3 can home the homeless right?.......right
