Veli Saçilik has been arrested 17 times for peaceful protests in Turkey. On one occasion the prison thugs cut off his arm but that didn't stop him. Now Erdogan has accused him of being a member of a terrorist group.

When governments arbitrarily designate groups as "terrorist" with no need to prove it, any group could be unjustly labeled that way. Perhaps Professor Saçilik is guilty of being a member of a "terrorist organization" which isn't terrorist. People can be convicted unjustly in that way even in the US.

To designate an organization as "terrorist" is fundamentally unjust without a trial to determine whether it really is one.
