Your reply disturbs me too, Mr Bong.
One word against the other, yes. But again, as we have discussed
before, the extent of the injuries is very important. If, upon
receiving instant medical attention [in cases like this an
ambulance will most certainly be activated], it has been discovered
that the injuries are most severe, then an arrest will definitely
be effected.
So imagine if you suffered from a fellow driver's road rage - He
cut dangerously into your path, jammed the brakes, almost causing
an accident. You horned him obviously, he was seriously rattled,
stopped and exited his car, waving a golf club. Before you realised
it, he smashed your windscreen and tried beating you with it. But
then the police arrived, and he promptly tossed the golf club back
into the concealment of his trunk and acted calmly, all before the
police had a whiff of what transpired.
So despite your protestations, he calmly refutes your 'wild claims'
and spins a different story, painting you as the aggressor, all the
while cooperating with the police and despite the fact that your
windscreen is the one that is clearly shattered. 
Obviously, without further evidence, he's not gonna get arrested,
and subsequent court proceedings will be lengthy, draggy and above
all costly, despite the fact that you are perfectly innocent.
Seriously speaking, under normal circumstances, how would a
normal person smash another's windscreen? certainly not barehanded,
no? even if he did it barehanded, literally, there would definitely
be marks on his hands to prove it, wouldn't it? Since it would take
a pretty substantial amount of force to break glass.
A broken windscreen is not a normal thing. So definitely the police
will believe the word of the victim who said that the aggresor used
a golf club or whatever to break his windscreen. a search on the
vehicle will then be conducted, to see just what it is that was
used to break the windscreen. again, analyzing the situation and
application of initiative/discretion will come to the fore
here.
In this particular scenario that you have described, the police
would by then have discovered the golf club, much with the victim's
help. by now, there will be a much clearer picture of who is the
victim and who, the perpetrator, wouldn't it? So, upon recording
statements of both parties, an assessment of the damage done, any
injuries to both parties, and bearing in mind the usage of the golf
club, as well as the fact that the aggresor waved a golf club and
tried to beat the vicitm with it, the only conclusion any sane
person can foresee is this:
that the perpetrator be arrested on the spot for criminal
intimidation, sec 506 of the penal code [cap 224]. for there is a
very real threat on the victim's life.
this, Mr Bong, is not a road rage case. this is a very serious,
life-threatening case of criminal intimidation, in which the police
can and definitely will effect an arrest immediately. 
The 2nd item you mentioned was that lashing out at police officers
is misdirected rage. True, but being the best people to determine
what should or should not be done during an incident, aren't they
in the best position to decide and advise lawmakers? Or have they
adopted the 'mind my own business and just follow procedure'
mindset? Even if they believe it to be wrong?
Like i said earlier, i don't blame officers for being absent 95% of
the time, but failing to repond adequately during the remaining 5%
doesn't really make my streets any safer either.
issues regarding our nation's laws are being brought up every
day. but whether the lawmakers do something about it or not is a
totally different thing altogether.
