for a family visit and also brought my laptop with me. For what its worth, during re-entry check at JFK, I was not searched at all, nor any questions about my laptop. The agent was actually very polite and asked "Did you enjoy your trip?"
I was not looking forward to the re-entry check, but it was smooth sailing - Last time I visited Pakistan (2 years ago), upon re-entry I had to go to the special Homeland Security check room and was questioned quite a bit, but they never checked my laptop.
Anyhow, considering I traveled to what is perceived as a dangerous country, I was pleasantly surprised that I was not subjected to such a scrutinizing search of my belongings. I'm guessing that the searches are somewhat random..?
