@DavidSupportsMonica agreed, esp. in Singapore, but why that quote then?

Because, I imagine, some people are unwise and too trusting. Why else? Your question should in addition have a third bullet point as possible: • Arrest or cite the passenger if the object or substance is not permitted in Singapore.

@DavidSupportsMonica why don't they write ~"passengers must only bring their own luggage, and not somebody else's" instead then?

Because sometimes it might be reasonable to bring something that belongs to, say, a family member, and you must always declare it.

@WeatherVane thanks, in that case, are those family luggage treated the same way as the passenger's own luggage?

No, they are treated the way that it says in your question.

@WeatherVane after declaring them at the Red Channel, what happens? Esp., what happens one indicates one doesn't know what it contains? Just more thorough checks + ticket to jail if something bad is found, as if one's own luggage went in secondary inspection?

I imagine, that they look inside the luggage.

My man, you always asked the stupidest questions, I guess it's your brand by this point.

@chx there are no stupid questions, only stupid people 👍

That's some #SelfAwarewolves moment if I've ever seen one. I have not called you stupid only your questions.

Laws often contain redundant duplication. Think of the common phrases "aiding and abetting" and "assault and battery".

Capital punishment is a legal penalty in Singapore. Executions are carried out by long drop hanging, and usually take place at dawn on a Friday. 33 offences including murder, drug trafficking, terrorism and use of firearms warrant the death penalty under Singapore law. The most recent executions to be conducted in Singapore were on 7 July 2022, when 31-year-old Malaysian Kalwant Singh Jogindar Singh and 48-year-old Singaporean Norasharee bin Gous were both hanged for trafficking over 120g of heroin.

@badjohn thanks, what's duplicated?

@FranckDernoncourt I thought that you were puzzled at the redundant instructions for unknown items when you must only bring your own luggage. One rule only applies if you have already broken the other.

@badjohn Thanks, I'm puzzled by "carrying an item for someone else, but you do not know what it contains". I don't think that would fly well if I said that to the US customs. I wonder how the Singapore customs would react to it.

@badjohn FYI shouselaw.com/ca/blog/criminal-defense/…

@FranckDernoncourt An interesting question. My guess would be very badly. I have not been for a long time but I remember the landing cards. One side said "Welcome to Singapore" and the other "Death to drug traffickers". An amusing contrast.

@FranckDernoncourt Yeah, aiding and abetting are similar but not identical. I thought that the reasoning was just to minimise loopholes.
