I agree with Mr Seah Yam Meng that we have to closely study ways to counter the threat of speeding trucks hurtling into revellers ("Not enough to guard against guns, explosives"; Monday).
To minimise such a threat, we can make roads near major events car-free.
Our experience in organising car-free days will come in handy; road blocks and contingency plans in the event of an attempted breach also have to be robust.
To prevent unduly alarming or inconveniencing the public, such initiatives for lower-risk events should be done with a light touch, such as being just truck-free.
