It would be wrong to generalise and say that those who bought into JB take security lightly. Instead we manage the risks as best as we can. Take the usual common sense measures. Try not to stand out and be a walking target. Keep kids close to you etc etc.
I wait for the correct time to consider my move to JB when kids are more or less out of the way, thankfully my "kids" are 20 and 17, boy is in NS HT training as a police man and girl in Melbourne now as a citizen, that is why the priority now is a home in Melbourne.
Next phase is JB retirement planning in a 5 year horizon. This would coincide with my boy finishing NS and uni, my plan may be to put him in the HDB in Singapore while we retire in JB, not fair to make him travel up and down everyday to work if he were to follow us to JB, as transport would be a problem, I would try to avoid owning an SG plate car in JB to keep low profile and get an MY registered vehicle and my son cannot use it to commute as Singaporean cannot drive MY car in Singapore.
Jury is still open with regards to landed property purchase, if choosing to live in condo, then no brainer for me to rent.
