This kind of thing is scary for passengers like me. Graffiti is fine, but thank goodness it was not anything worse. The last time the breach was at Changi Depot and this time it was at Bishan. What’s up with our security? Makes me think that privatization of transport is not good at all. The last time SMRT was fined S$50,000 for the security lapse which doesn’t seem much to me for such a big company.
