GRRR indeed, I can only hope the translation is badly worded and incomplete.
See to those responsible and punish, yes, - but more importantly - ffs enforce whatever laws/regulations you have in relation to this tragedy so that it doesn't happen again.
Sad to say, but my Thai friends say this will be forgotten in a week, it's not the first time it's happened and will not be the last.
It's almost always the lowest hanging fruit in the kingdom of Siam.
