confusing-political-arrest-of-deaf-man

There is so much political unrest in Belarus.
People are revolting against dictator Alexander
Lukashenko. It was so bad that a deaf man, with
no speaking skills, was arrested. What was his
crime? Shouting out anti-government comments!
How can he be shouting out such comments if he
has no speaking skills at all? This is how bad
things are at Belarus.
