When in-country, Todd's followed the rules. They were in Singapore to collect their son's possessions, and they did that. This saved the Singapore police and/or the landlord from having to sell or throw away those possessions. If there were any way for them to do the police's job of investigating the incident, I'm sure they would have attempted that as well, since clearly the police abdicated that responsibility.

Now they're in the USA, and Singapore's rules no longer apply to them.

The police can do anything with a disk image they could have done with the original disk, except tamper with the evidence. If they still claim to require the original disk, that clearly demonstrates their intentions.
