for what reasons why must you say that?! 
================
For this issue, I think the cabby who whacked the Yio Chu Kang MP
must be very stressed (at the time of incident), burdened by lots
of unhappiness at his workplace (i.e. high fuel price, high cab
rents, low income, and encountered with too many undersirables etc
etc).......and rants.......
Nowadays, life as a cabby must be very tough for them...........to
that they could not express their rants (and
unhappiness).........
So, if they could not find any means to express any unhappiness,
they may resort to extreme means.......like whacking important
characters etc etc.........
Still, the cabby should relate his problem to the MP in a peaceful
manner, not violence. The outcome would be very different in this
case..........had the cabby be peaceful in handling his
anger.
Violent acts cannot be condoned!
(according to shin min daily today's issue, it was said that this
particular cabby was requesting the MP to help him restore his
VL..............
I think now this particular cabby kanna detained..............and
interrogated......)
