Some from the pro-PAP camp have been trying to defend the slip-up by producing an anti-crime spin. "You mean you don't want the police to have access to all available means to deter crime? You must really want to impede criminal investigations." This is disingenuous. The folks saying this now are merely trying to ex-post rationalise the need for the TraceTogether apps. If that really was a credible strategy to combat crime, these folks would've been clamouring and supporting such personally intrusive tracking methods for a long time coming now.
On the other hand, I have no illusions that those from the anti-PAP camp who've been dumping on the government really give a crap about privacy rights. How could they possibly? You've never heard these guys so much as mention privacy issues before TraceTogether. They're dumping on the PAP because it's a golden opportunity to score political points.
In other words, partisan hacks at play on both sides. Remember that democratic politics is not about principles, it's about power. Anyone who takes sides and puts too much faith in their "own team" are setting themselves up to be blinded by their own prejudices. Partisanship is effective politics, principled consistency is not.
Also doesn't the recently proposed legislation that specify clearly the types of crimes TT data can be used for contradict the idea that TraceTogether technology is "primitive" and "basic", that the police has far more advanced methods for crime fighting? If that was true, why would they not just scrap these exceptions in the wake of this scandal?
