Prime Minister Prayut Chan-o-cha has shown he is very aware of the recent protests that have criticised his national administration. Gen Prayut has said that if the National Council for Peace and Order (NCPO) lifts the ban on political activities, there could be "trouble". Among these specific rights and liberties are (Section 34) "to express his opinion, make speech, write, print, publicise". This applies to any group of five or more people for any political discussion -- or protest. This is more than enough restriction, and gives an excellent reason to lift the ban on gatherings of five or more people.
