Sinkies are too meek, too docile. If they were more xenophobic and assertive enough, these things would not have happened.
See lah, now foreigners of all nationalities know Sinkies can be easily bullied into submission, and on top of that the kangaroo courts dare not touch foreigners. This will only embolden the foreigners to be more arrogant, more condescending and more spiteful. It could be a Facebook comment, a Youtube video, an ang moh cyclist on the roads giving you the finger, a company's HR department hijacked by FTs, getting groped inside MRT trains, unhygienic food sellers of a certain nationality... the list goes on and on.
The meek shall inherit nothing, Sinkie fools. If you don't stand up for yourself, you can only expect to be trodden underfoot.
