I hope targeting bitcoiners won't become a new trend for criminals.
Believe me, it would.
It has been started.
And seriously, what's the best practice to prevent such cases, when you hold/have access to significant amount of bitcoins? Sure you could hide your private key (or part of it) in some secure place outside of your home, but then the risk of you (or your family) getting tortured or even killed increases. Well organised group as described above unlikely would be happy to leave with nothing.
The thing that we can do is to protect our anonymity at all costs. They won't know who you are if you didn't share your identity with the public (internet) for free or easily.
And what about exchanges? 2FA is a prevention from hacking, but won't work at all if you're held at gunpoint. I'd be very happy to see some extra (opt-in) security features on exchanges, i.e. few days delay in withdrawing BTC above certain amount.
Duh, 2FA supposed to be safe as long as the access to your device is in your own hand.

This would make things more complicated to do.
Frankly, I think this kind of event is making me more certain that Bitcoin is a real currency.
