JAKARTA (JP): What should a soldier do before firing tear gas
at demonstrators outside the People's Consultative Assembly
(MPR)? Pull out his handkerchief, of course.

Antara observed that soldiers attempting to disperse
protesters with tear gas suffered from the consequences of their
own action.

In the late afternoon on Friday, while stinging white clouds
of tear gas billowed skyward, watery-eyed soldiers were seen
clamping handkerchiefs over their faces.

Sadly it was too little too late, with some of the poor
soldiers succumbing to convulsions of sneezing as if suffering
from a bad flu.
